Products

• Precision Kinematic Mirror Mounts (KS Series) — ThorLabs: Three adjuster kinematic mirror mounts with a thicker back plate and stiffer springs than the standard two adjuster design. 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) — ThorLabs: 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) — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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) — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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) — ThorLabs: 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 — ThorLabs: 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) — ThorLabs: 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) — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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) — ThorLabs: 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) — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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) — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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) — ThorLabs: 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 — ThorLabs: 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.
• KPC101 K-Cube Piezo Controller and Strain Gauge Reader — ThorLabs: A single channel piezo drive and strain gauge readout in one compact cube, running open loop on voltage or closed loop on position. Digital triggers make it suitable for piezo scanning applications.
• MDT693B and MDT694B Open-Loop Piezo Controllers — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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 — ThorLabs: 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.
