Light Analysis
Welcome to Thorlabs; below you will find links to detectors and instrumentation that measure the various properties of light, a subset of our entire line of photonics products. Thorlabs offers an extensive selection of instruments that measure the properties of light. Our versatile power and energy meters can be used with over 25 different sensors in order to make NIST-traceable power and energy measurements. If the convenience of a meter is not desired, our selection of detectors includes basic photodiodes (uncalibrated and calibrated), photodetectors (biased, amplified, and avalanche), CCD and CMOS arrays, position detectors, integrating spheres, and photomultiplier tubes. The Beam Characterization category contains beam profilers (camera and scanning slit), a wavefront sensor, spectrometers, and interferometers, while the Polarimetery link leads to a selection of instruments used to measure and control the polarization of light.

Optical Power And Energy Meters
-
Thorlabs' expanding line of optical power and energy meters includes power meter consoles, a large selection of sensor heads, a wireless power meter with a built-in photodiode sensor, and a fiber optic power meter designed for use in the field. The consoles (PM100, PM400, and PM300 Series) when paired with our extensive line of power and energy sensors provide calibrated (NIST traceable) measurements across a broad range of powers, energies, and wavelengths. The console(s) and sensor(s) can be purchased individually or as bundles based on our most popular console and sensor pairings. The sensor calibration data is stored in the sensor head and is automatically read by the console, which allows the user to use multiple sensors with the same console. Compatible sensors are easily identified by the red c-series connector. All of our old A/B-Type sensors are available with the new connector; plus, we have continued to expand our power and energy sensor product lines.

Detectors
-
Thorlabs' photodetectors are capable of detecting light throughout the UV, VIS, NIR, IR, and THz spectral regions. Our photodetectors feature sensors that enable properties such as intensity, power, intensity distribution, wavefront shape, energy, and wavelength to be measured. We offer unmounted photodiodes as well as amplified, biased, and avalanche photodetectors. Thermal power detectors are available unmounted, mounted on a PCB, or mounted on an aluminum plate. Also available are position-detecting sensors, integrating spheres, and an acoustic detection module.

This page features the optics and instrumentation necessary to control and measure the polarization of light. Our free-space and fiber-coupled polarimeters can measure any state of polarization (SOP) on the Poincaré sphere.
