Reflective Condenser
-
Reflective condensing system and focusing accessory for coupling light sources to monochromators. It uses two mirrors to focus to the entrance slit. The reflective system eliminates chromatic aberration, provides maximum spectral range, and does not require refocusing. Accessories like light choppers and filter wheels can also fit inside next to the slit. Versions with rotatable mirror available for up to four source direction.

Optical Chopper
-
These high stability variable frequency optical choppers each include a set of chemically blackened photoetched chopping discs. The mini chopper is an excellent choice for applications requiring a compact package. The chopping discs come in a variety of slot apertures and allow operation. Beam diameter is limited to 0.75mm when using the 200-slot disc and 1.0mm when using the 40 slot mini disc. The easy-to-interchange blades are made of non-magnetic, half hard brass and can be used in combination. Chopping frequency is set by adjusting a ten-turn dial or by applying an external DC voltage to the BNC input. Reference output is a TTL pulse and is in-phase with chopping action. The 5 digit led display gives a direct read-out of the chopping frequency. Power: 90-130V or 180-260V; 50/60Hz; 12VA max. Power supply included. Choppers are often used together with lock-in amplifiers.

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.
