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.

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.

Light Simulator
-
From the review of the scientific development history, reliable and stable artificial light sources have played a very important role in the past century. For example, the artificial solar simulator is an important part of simulating sunlight to ensure accurate performance of PV characterization. With the growth of light sensor applications, more and more requirement of light simulators (or artificial light sources) explored. One of the core technologies of Enlitech is the artificial light sources. We can manipulate different lamp types (short arc lamps, LEDs, filament lamps et. al.) to generate different spectrum-form in different light intensity levels, beam sizes, and wavelength ranges. We have launched different artificial light source products for different applications fields. For instance, SS-X series solar simulators and ILS-30 ambient light simulator are for the PV field, HAAS is highly accurate star light simulator for the space field, and ALS-300 is a general-purpose light source in science research field. These products can not only meet the needs of your application, but also speed up the process of your research or mass-production.
