Aspheric Condenser Lenses (ACL Series): Large aperture aspheres in B270 crown glass, shaped for collecting and collimating light from LEDs, lamps and other extended sources. High numerical apertures gather a wide cone of light with far less spherical aberration than a spherical condenser.
Diffraction-Limited High-Precision Aspheres, MRF Polished (AL Series): Magnetorheologically polished aspheric lenses in N-BK7 or S-LAH64 that reach diffraction limited performance. They focus or collimate a laser beam in a single element and are used where a doublet would add too much wavefront error.
Plano-Convex Cylindrical Lenses, N-BK7, Uncoated: Cylindrical lenses that focus or magnify in one axis only. They are used to circularise the elliptical output of a laser diode, form a line focus and give anamorphic beam shaping on an optical bench.
Protected Silver Mirrors (PF Series, P01 Coating): Metallic mirrors with a silver coating and a silicon dioxide overcoat, giving the highest visible and near infrared reflectance of any Thorlabs metallic mirror. Round, square and rectangular formats are stocked, and the broad response suits femtosecond pulses.
Protected Gold Mirrors (PF Series, M01 Coating): Gold coated mirrors with a protective dielectric overcoat, intended for infrared work where reflectance must stay high well beyond 2 micrometres. Reflectance is relatively insensitive to angle of incidence, as with other metallic coatings.
Protected Aluminum Mirrors (PF Series, G01 Coating): General purpose broadband mirrors with an aluminium coating under a silicon dioxide protective layer. They tarnish less readily than protected silver in humid conditions, which makes them a practical teaching laboratory mirror.
Fused Silica Broadband Dielectric Mirrors (BB Series): Dielectric coated mirrors on fused silica substrates that reflect more than 99% for both polarisations over four broad bands. They are designed for continuous wave and nanosecond lasers at angles of incidence from 0 to 45 degrees.
Off-Axis Parabolic Mirrors, Protected Silver Coating (MPD Series): Diamond turned off-axis parabolas that focus a collimated beam or collimate a point source without spherical or chromatic aberration. The off-axis geometry moves the focus clear of the beam path, which is useful for spectroscopy and ultrafast work.
Right-Angle Prisms (PS Series): High precision prisms that turn a beam through 90 degrees by total internal reflection at the hypotenuse, or retroreflect it through 180 degrees. They are a standard classroom demonstration of total internal reflection as well as a beam folding component.
Equilateral Dispersive Prisms (PS Series): High index prisms with a low Abbe number, used to disperse white light into a spectrum with less stray light than a grating and no higher diffraction orders. They are normally used at the minimum angle of deviation.
Glan-Taylor Calcite Polarizers (GT Series): Air-spaced birefringent prism polarisers made from laser quality natural calcite, producing very pure linear polarisation. The ordinary ray leaves through a side port, so only the transmitted extraordinary beam should be used.
Nanoparticle Linear Film Polarizers (LP Series): Sheet polarisers made from nanoparticles in sodium-silicate glass, covering the UV through to the mid infrared in eleven wavelength bands. Mounted versions thread into SM lens tubes and rotation mounts for polarisation experiments.
Non-Polarizing Cube Beamsplitters, 400 to 700 nm (BS Series): Cemented N-BK7 cubes that divide a beam with little dependence on its polarisation, in five split ratios. The single reflecting surface avoids ghost images and the cube geometry keeps the transmitted beam free of lateral offset.

Sizes cover half inch to 4 inch optics, with lockable and differential adjuster versions for beam steering that must hold alignment over long periods.
Kinematic Mirror Mounts with Two Adjusters (KM Series): The general purpose two adjuster kinematic mount used across most teaching and research optical benches. Versions take 7 mm to 2 inch optics with either double-bore setscrew retention or an SM-threaded bore for thin optics and threaded components.
Compact Kinematic Mounts (KMS, KMSS and QM1): Small footprint kinematic mirror mounts for optical systems where space is tight. The KMS uses removable knobs over a hex socket and the slimmer KMSS is hex driven only, both taking mirror holders for half inch or one inch optics.
Polaris SM1-Threaded Low-Drift Kinematic Mirror Mounts: Heat treated stainless steel kinematic mounts built for long term pointing stability, with sapphire adjuster seats and matched 100 TPI actuator and body pairs. The SM1-threaded bore takes one inch optics, lens tubes or other threaded components.
Gimbal Mirror Mounts: Mounts that rotate the optic about the centre of its front surface, so beam steering produces no translation and very little crosstalk between axes. Manual models cover one inch and two inch optics, and a piezo driven version is available for fine remote control.
Fixed Mirror Mounts (FMP and MFM Series): Non-adjustable mounts for holding mirrors, windows and other flat optics at a fixed angle. A nylon-tipped setscrew secures the optic and a tapped hole on the base takes a standard post, giving a low cost way to fix optics that need no alignment.
Ø1" (Ø25 mm) Post Holders: Post holders for one inch diameter optical posts, using a flexure clamp that grips the post along two contact lines. They give height adjustment with the stability of a pillar post and are offered in four lengths with a bottom tapped hole or pedestal base.
Ø1" (Ø25.0 mm) Pedestal Pillar Posts: One piece non-magnetic stainless steel posts, precision ground to 25.0 mm diameter and tapped at both ends so they stack. The pedestal base works with clamping forks, giving a rigid way to set optic height on a table or breadboard.
Ø1" SM1 Lens Tubes: SM1 threaded lens tubes that take one inch optics directly and build light-tight optical subassemblies. The 1.035 inch-40 thread standard runs through most of the Thorlabs range, so tubes, mounts, adapters and cage plates all interlock.
Adjustable SM1 Lens Tubes: Lens tubes that translate an optic along the optical axis inside an SM1 assembly. Rotating versions give simple travel while the SM1ZM and SM1NR zoom housings use a helical drive so the internal cell moves without rotating, which matters for polarisation optics.
XE25 25 mm Optical Construction Rails: Extruded aluminium rails with a 25 mm square profile and channels on all four faces, used to build enclosures, frames and rigid mechanical structures on an optical table. T-nuts in the channels accept any 8-32 or 1/4 inch-20 optomechanical component.
Manual Rotation Mounts, High Precision (PRM Series): Rotation mounts that combine continuous 360 degree coarse rotation with a locking dial and backlash-free fine adjustment. They are the standard way to set the angle of polarisers and wave plates in half inch, one inch and two inch sizes.
MC2000B Optical Chopper System and Chopper Wheels: A microprocessor controlled optical chopper that modulates a continuous beam for lock-in detection. A crystal-stabilised phase-locked loop holds the chopping speed and phase against a reference, and fifteen blades cover the full frequency range.
Motorized Filter Wheels, Stepper Motor Driven (FW102C and FW212C): Stepper driven filter wheels with an integrated controller, taking six one inch filters or twelve half inch filters. Filters can be changed by hand at the housing or driven remotely over USB, RS-232 or a BNC trigger for automated measurement sequences.
Fiber Coupling and Spatial Filter Systems (KT120 and KT311): Prebuilt optomechanical assemblies for launching a free space laser beam into fibre and for spatial filtering. The KT120 uses high-precision differential adjusters for submicron translation, and the KT311 cleans up a beam to a near Gaussian profile.
LDM Series Temperature-Controlled Mounts for TO-Can Laser Diodes: Laser diode sockets with an integrated thermoelectric cooler for 3.8 mm, 5.6 mm and 9.0 mm TO can packages. An internal bias-T allows RF modulation of the diode current, and the housing threads into SM1 lens tubes and 30 mm or 60 mm cage systems.
Unmounted Achromatic Doublets, AR Coated 400 to 1100 nm: Cemented two element lenses corrected so that two wavelengths share a focus, which cuts chromatic and spherical aberration and gives a much smaller spot than a singlet. Supplied in half inch, one inch and two inch diameters.
Mounted Zero-Order Half-Wave Plates (WPH Series): Compound zero-order retarders made by pairing two multi-order crystalline quartz plates with crossed axes. The result rotates linear polarisation with much less temperature and wavelength dependence than a single multi-order plate.
Mounted Longpass Colored Glass Filters (FGL Series): Schott coloured glass longpass filters mounted in SM1 threaded rings so they screw into lens tubes and filter wheels. Each housing is engraved with the part number and cut-on wavelength, which makes them convenient for teaching laboratories.
TravelMax LNR25 Linear Translation Stages, 25 mm Travel, Manual: All steel manual translation stages on crossed roller bearings, offered with a micrometer or a differential drive. The rigid thermally matched construction gives uniform motion over the full range and the stages stack into XYZ configurations.
TBB Series Large-Area Translation Stages: Hand operated rack and pinion stages large enough to carry a whole experiment, with a deck height that matches standard breadboards. Fine adjustment is by hex key and the position locks with a setscrew.
GN and GNL Series Goniometric Stages: Stages that tilt an object about a fixed point above the mounting surface, so the sample stays in place while its angle changes. Two models can be stacked in an XY configuration sharing the same point of rotation.
6-Axis NanoMax NanoPositioning Flexure Stages (MAX600 Series): Parallel flexure stages that give six independent degrees of freedom about a common pivot point, which simplifies alignment and reduces crosstalk. Micrometer, stepper and piezo drive options cover coarse travel down to nanometre steps.
M30X and M30XY Kinesis 30 mm Motorized Translation Stages: Single and dual axis motorised stages with the DC servo drive electronics built into the stage body, controlled from a PC over USB. External triggering allows them to be synchronised with cameras and detectors during a scan.
PRMTZ8 Motorized Precision Rotation Stage: A compact DC servo driven 360 degree rotation stage with a tapped platform for prisms, polarisers and other optics. A home limit switch locates zero, and the vernier scale allows manual readout of the angle.
DDR100 Direct Drive Rotation Stage: A low profile rotation stage driven by an integrated brushless DC motor with no leadscrew, so there is no backlash. High speed and a central SM1 threaded aperture suit polarisation scanning and sample rotation.
ORIC Rotation Stages with Piezoelectric Inertia Drive (PDR Series): Compact stainless steel rotation stages driven by a piezoelectric inertia motor, giving fine backlash-free steps and holding position with power off. A central bore lets a beam pass through or takes optomechanics.
UMC Series Universal Motor Controllers: Benchtop controllers in one, two and three channel versions that drive both brushless DC and stepper motor stages with encoder feedback. They run from a PC over USB or Ethernet, from a joystick, or from the XA software suite.

MDT693B and MDT694B Open-Loop Piezo Controllers: Low noise voltage sources for driving piezoelectric actuators and stacks, in one and three channel versions. The maximum output can be limited by a rear switch to protect low voltage piezos, and BNC input allows external modulation.
BPC301 and BPC303 Closed-Loop Piezo Controllers: High power benchtop piezo controllers that run open or closed loop with strain gauge or capacitive sensor feedback. Waveform generation supports piezo scanning, and an auto-configure function reads Thorlabs actuator identification.
DRV120 Modular Piezoelectric Actuator: A piezo drive that fits between a NanoMax stage and its existing actuator, adding fine travel with strain gauge feedback for closed loop control. It also fits any stage that accepts a 9.5 mm mounting barrel.
PIA Series Piezoelectric Inertia Actuators: Stick-slip piezo actuators that replace a manual adjuster on a mirror mount or translation stage, giving nanometre steps over a long travel range with no backlash. They hold position without power once stepping stops.
Amplified Piezoelectric Actuators, 220 µm to 2500 µm Travel: Discrete piezo stacks mounted inside a flexure housing that acts as a lever, greatly increasing the free stroke while keeping the fast response of the stack. They are backlash free and suitable for open or closed loop use.

Nexus Optical Tables, 310 mm (12.2") Thick: A thicker Nexus optical table for demanding beam stability, offered from 1 m x 2 m up to 1.5 m x 4 m. The 310 mm core raises stiffness so that deflection under a 150 kg central load stays below 1.2 micrometres, suiting interferometry and long beam paths.
Nexus Optical Tables, 460 mm (18.1") Thick: The heaviest Nexus table, 460 mm thick, available from 1.2 m x 2 m up to 1.5 m x 4 m. The extra depth gives the highest stiffness in the range and is intended for large multi-instrument setups where relative tabletop motion must stay at the sub-nanometre level.
Nexus Optical Breadboards, Optimized Damping, 60 mm (2.4") Thick: Steel honeycomb breadboards 60 mm thick, from 300 mm x 300 mm up to 900 mm x 1200 mm. Each board is individually tested and damping is optimised per size, making them a practical mounting surface for benchtop optics and small laser setups.
Nexus Optical Breadboards, Optimized Damping, 110 mm (4.3") Thick: A 110 mm thick Nexus breadboard range covering 600 mm x 900 mm up to 1200 mm x 1800 mm. The deeper honeycomb core raises stiffness for larger optical layouts that still need to sit on a frame rather than a full optical table.
Aluminum Breadboards: High Stiffness, 25 mm (0.98") Thick: Lightweight non-magnetic breadboards built from aluminium plates over an aluminium honeycomb core. Matching the coefficient of thermal expansion throughout reduces thermal drift, and a T-slot in each side accepts 25 mm construction rails.
Upgradeable Optical Table Supports: Rigid, Non-Isolating: Free-standing rigid legs for Thorlabs optical tables, supplied in three heights with a levelling pad. They suit vibration-insensitive work such as general spectroscopy, and each leg can later be converted to passive pneumatic isolation with an upgrade kit.

PDA Series Si and Black Si Free-Space Amplified Photodetectors: Silicon photodetectors with a built-in transimpedance amplifier, in fixed gain, switchable gain and USB data acquisition versions. They are the workhorse detector for laser pulse monitoring and general laboratory photodetection.
DET Series Free-Space Biased Detectors: Reverse biased photodiodes in a slim aluminium housing for monitoring continuous wave or fast pulsed lasers. Silicon, germanium and InGaAs versions cover the UV to the mid infrared, and each unit ships with an internal 12 V bias battery.
PDB Series Free-Space Balanced Amplified Photodetectors: Balanced receivers that subtract two optical inputs to cancel common mode noise, letting small signal changes be pulled out of the noise floor. They are used for spectroscopy, heterodyne detection, optical coherence tomography and terahertz work.
SPDM Series Single Photon Detectors and Counting Modules: Actively quenched, temperature stabilised silicon avalanche photodiode modules that produce a TTL pulse for every detected photon. They pair with correlated photon pair sources for quantum optics teaching, and also suit photon correlation spectroscopy and LIDAR.
Photomultiplier Modules (PMT and PMM Series): Photomultiplier modules with bialkali, multialkali or GaAsP photocathodes for detecting faint optical signals. Their large active areas suit divergent light, and SM1 or C-Mount threading lets filters and lens tubes attach directly.
Position-Sensing Detectors (PDP and PDQ Series): Detectors that report the position of an incident beam rather than just its power. The lateral effect PDP90A is insensitive to beam shape, while the segmented quadrant models suit automatic alignment and beam stabilisation loops.
General-Purpose Ø50 mm Integrating Spheres (2P Series): Integrating spheres in black anodised aluminium that spread incoming light evenly by multiple internal reflections. They are used for laser power, flux, reflectance and radiance measurements, and take Thorlabs SM05PD photodiodes directly.
Zelux 1.6 MP CMOS Compact Scientific Cameras: Very small scientific cameras with a 1.6 megapixel global shutter CMOS sensor, in monochrome and colour. They connect over USB 3.0, thread directly into SM1 lens tubes and 30 mm cage systems, and ship with ThorImageCAM software and an SDK.
Kiralux CMOS Compact Scientific Cameras: A family of global shutter CMOS cameras from 1.3 to 12.3 megapixels in monochrome, colour and NIR-enhanced versions. Passively cooled and thermoelectrically cooled models are offered, all with a USB 3.0 interface and cage system compatibility.
Quantalux 2.1 MP sCMOS Scientific Cameras: Monochrome scientific CMOS cameras built for low light imaging, combining sub-electron median read noise with high dynamic range. They are used for fluorescence microscopy, quantum dot imaging and multispectral work, in passively or actively cooled packages.
Kiralux Polarization Cameras, 5.0 MP Monochrome CMOS: Monochrome cameras with a four-direction wire grid polariser array built onto the sensor between the microlenses and the photodiodes. A single exposure yields intensity, azimuth and degree of linear polarisation images for stress and flaw inspection.
EDU-QOP1 Quantum Optics Educational Kit: A free space kit that lets students build a heralded single photon source from a type-I BBO crystal and study it with single photon detectors. Experiments cover coincidence counting, single photon polarisation, self interference and the quantum eraser.
EDU-QCRY1 Quantum Cryptography Analogy Demonstration Kit: A classical analogy kit that models the BB84 key distribution protocol using the polarisation of light. Students build the sender, receiver and eavesdropper stations and see how interception introduces detectable errors.
Quantum Eraser Demonstration Kit: An analogy experiment built around a Mach-Zehnder interferometer, in which polarisation marks which path the light took and then erases that information. The fringes disappear and reappear, showing complementarity in a form students can see.
EDU-BT1 Bomb Tester Demonstration Kit: A Michelson interferometer kit that demonstrates the Elitzur-Vaidman interaction-free measurement thought experiment. Marking a photon with path information destroys the interference pattern, which students observe on a screen and with a detector.
EDU-OT3 Portable Optical Tweezers Educational Kit: A teaching optical trap assembled on a 30 cm by 60 cm aluminium breadboard, with a visible laser, sample stage and camera. Students observe Brownian motion and trap microbeads in three dimensions without realigning the setup between sessions.
EDU-TRAS1 Time-Resolved Absorption Spectroscopy Educational Kit: A masters level kit for building a nanosecond transient absorption spectroscopy setup. Students measure the change in sample absorbance after optical excitation and extract excited state decay times.
EDU-FOP2 Fourier Optics Educational Kit: A 4f optical setup that projects the Fourier plane of a chrome-on-glass target onto a screen, so students can filter spatial frequencies and watch the image change. It links Fourier transforms to image formation in a microscope.
EDU-3D1 Polarization and 3D Cinema Technology Kit: A polarisation teaching kit that builds three setups for viewing 3D images, including a circular polarisation projection based on cinema technology. Further experiments measure optical rotation in sugar solutions and map stress in materials.
OTKB Modular Optical Tweezers: A complete inverted microscope optical trapping system for advanced laboratory courses and research. A 976 nm trap laser, oil immersion objective and piezo sample stage allow microscopic objects to be held and moved under video observation.
AOK Series Adaptive Optics Kits: Complete adaptive optics systems containing one or two deformable mirrors, a Shack-Hartmann wavefront sensor, a laser diode source, imaging optics and control software. They are used for beam shaping, microscopy and teaching demonstrations.
