Products

• CCT Series Compact Spectrometers — ThorLabs: Crossed Czerny-Turner spectrometers with a line array detector, an SMA fibre input and an internal shutter for fast background subtraction. Four models cover the ultraviolet through to the short wave infrared for absorption, emission and fluorescence work.
• OSA Series Optical Spectrum Analyzers — ThorLabs: Fourier transform based analysers that act as both a broadband spectrometer and a wavelength meter. Seven models cover 250 nm to 12 micrometres, taking either an FC/PC fibre input or a collimated free space beam.
• WM200 Series Wavemeters — ThorLabs: Instruments that measure the wavelength, coherence length and power of a laser to parts per million accuracy. An external reference input improves the figure further, which matters for laser locking and atomic physics work.
• SA Series Scanning Fabry-Perot Interferometers — ThorLabs: Confocal cavity spectrum analysers that resolve the fine structure of a continuous wave laser, including mode hops and linewidth. A piezo scans the cavity length and the transmitted signal is read on an oscilloscope.
• SI Series Shearing Interferometers — ThorLabs: Shear plate devices that give a quick qualitative check of whether a coherent beam is collimated. Fringes parallel to the reference line mean the beam is collimated, and rotated fringes show convergence or divergence.
• WFS Series Shack-Hartmann Wavefront Sensors — ThorLabs: Sensors that pair a CMOS camera with a photolithographic microlens array to measure the wavefront of a beam and decompose it into Zernike terms. They are used for optical alignment, adaptive optics and lens testing.
• BP209 Series Scanning-Slit Optical Beam Profilers — ThorLabs: Dual scanning slit heads that reconstruct the two dimensional intensity profile of a near Gaussian beam, with a knife edge mode for very small spots. They measure beam width and position to ISO 11146 for continuous wave and pulsed lasers.
• BC200 Series CMOS Camera Beam Profilers — ThorLabs: Camera based profilers giving a full two dimensional analysis of a laser beam, including single pulse capture. Supplied with neutral density filter sets, they cover the deep ultraviolet or the visible and near infrared.
• M2MS Complete M-Squared Measurement Systems — ThorLabs: Turnkey systems that measure laser beam quality, reporting M squared, divergence, focus diameter, waist position and Rayleigh length. Factory aligned optics and an internal translation stage automate the ISO 11146 measurement.
• PAX1000 Series Polarimeter Systems — ThorLabs: Rotating wave plate polarimeters that measure the full state of polarisation of a collimated or fibre coupled beam and plot it on the Poincare sphere. They also report degree of polarisation and extinction ratio.
• EDU-MINT2 Michelson Interferometer Educational Kit — ThorLabs: A teaching Michelson interferometer with laser and LED sources, so students can compare coherence lengths and produce white light fringes. It is also used to measure the refractive index of Plexiglas and the thermal expansion of an aluminium rod.
• XL-80 laser interferometer system — Renishaw: A laser interferometer for measuring and calibrating motion systems, machine tools and coordinate measuring machines. It measures linear, angular, rotary, straightness and squareness errors directly, giving traceable data that can be used to set machine compensation.
• XM-60 multi-axis calibrator — Renishaw: A laser system that measures errors in six degrees of freedom along a linear axis from a single set-up. It captures linear, horizontal and vertical straightness, pitch, yaw and roll together, so all geometric errors in an axis come from one measurement run.
• XM-600 multi-axis calibrator — Renishaw: The XM-600 delivers the full six degrees of freedom capability of the XM-60 system when used with CARTO software, and adds communication with Renishaw UCC controllers. It suits facilities that run both machine tools and coordinate measuring machines.
• XR20 rotary axis calibrator — Renishaw: A wireless calibrator for rotary axes on machine tools, stages and jigs. An integrated angular retroreflector sits on a servo controlled axis whose position is read by a high accuracy encoder machined directly onto the main bearing, and it works with XL-80 and XM-60 lasers.
• QC20 ballbar — Renishaw: A telescoping ballbar with precision balls at each end that measures small changes in radius while a machine tool follows a programmed circular path. It shows up geometric, dynamic and play related positioning errors in a test that takes ten to twenty minutes.
• XK20 alignment laser system — Renishaw: Renishaw's second generation alignment laser system for machine build and service. It measures straightness, parallelism, squareness and level on linear and rotary axes, and reports to ISO 230-11 through the CARTO XK20 app, which also carries ISO 10791 and 3070 tolerances.
• XK10 alignment laser system — Renishaw: A digital alignment laser system used to measure and adjust geometric and rotational errors while a machine is being built or serviced. It replaces dial gauges, autocollimators and metrology artefacts for checking that rails are straight, square, flat, parallel and level.
• RESOLUTE optical absolute encoder series — Renishaw: A true absolute optical encoder for linear, partial arc and rotary axes. Position is known at switch-on without any movement, and low sub-divisional error with very low jitter gives smooth velocity control in demanding motion systems and nano-positioning stages.
• EVOLUTE optical absolute encoder series — Renishaw: A true absolute optical encoder built on RESOLUTE technology but using a 50 um scale period, which gives wider installation tolerances and better resistance to contamination. Position is available immediately at start-up without any axis movement.
• QUANTiC optical incremental encoder series — Renishaw: A compact incremental open optical encoder with digital or analogue output. It has wide installation and operating tolerances, built-in calibration functions and linear or rotary scale options, which makes it straightforward to fit on production machinery.
• TONiC optical incremental encoder series — Renishaw: A compact non-contact incremental encoder for highly dynamic precision motion. Filtering optics in the readhead give very low jitter and low sub-divisional error, and the external Ti interface takes the resolution down to 1 nm for linear, partial arc and rotary axes.
• VIONiC optical incremental encoder series — Renishaw: Renishaw's highest performing incremental open optical encoder, giving digital position feedback direct from the readhead. Filtering optics and on-board interpolation produce very low sub-divisional error without needing an adaptor or separate interface unit.
• ATOM DX optical incremental encoder series — Renishaw: Renishaw's smallest incremental optical encoder with digital output taken straight from the readhead. Filtering optics and interpolation are built into the miniature body, which suits space constrained instruments and stages where performance cannot be reduced.
• ATOM optical incremental encoder series — Renishaw: A miniature non-contact optical incremental encoder for linear and rotary applications where space is tight. Digital output comes from a choice of high-speed interpolator interfaces, and an integrated LED shows signal integrity during installation.
• FORTiS enclosed optical absolute encoder series — Renishaw: A sealed linear absolute encoder that puts RESOLUTE technology inside a rigid extrusion for use in harsh environments such as machine tools. Tuned mass dampers in the readhead raise vibration resistance, and the non-contact design avoids mechanical wear.
• ASTRiA inductive rotary absolute encoder series — Renishaw: An inductive rotary absolute encoder that reads a multi-track scale on a passive rotor using electromagnetic induction. Because it needs no line of sight it tolerates dirt and oil, and built-in alignment flexures self-centre the rotor so no calibration is required.
• RLE fibre optic laser encoder system — Renishaw: A homodyne laser interferometer system for position feedback, made up of an RLU laser unit and one or two RLD10 detector heads. Fibre optic delivery keeps heat away from the axis, which suits semiconductor stages and other high precision positioning work.
• HS20 long range laser encoder — Renishaw: A laser head that works with an external linear optics kit to form a non-contact interferometric encoder for long axes. It gives sub-micron position feedback on large machine tools and removes the hysteresis, backlash and cyclic errors of rack and pinion or ballscrew feedback.
• RMAP multi-axis periscope — Renishaw: A periscope that lets three RLD10-X3-DI differential interferometer heads measure linear position, pitch and yaw along one axis of a high performance XY stage. The small beam footprint keeps the target mirrors light, and it bolts to a vacuum chamber or metrology frame.
• AutoRAE 2 Automatic Test and Calibration System — Honeywell: Modular bump test and calibration station for RAE Systems gas monitors. It runs as a single bench unit or networked to support up to ten cradles at once and calibrate for up to five distinct gases, with one touch bump testing.
• MicroDock II Dock Calibration System 3 inlet — Honeywell: Portable automated test and calibration station for Honeywell portable gas detectors, in a three gas inlet configuration. It needs no computer, expands by adding modules and runs bump tests and calibrations on several instruments at once.
• MicroDock II Dock Calibration System 4 inlet — Honeywell: Portable automated test and calibration station for Honeywell portable gas detectors, in a four gas inlet configuration. Fully portable and expandable, it manages bump testing and calibration without a connected computer.
