Ophir Laser Measurement Group announces fast photodiode detector for pulsed lasers

Ophir Laser Measurement Group, Logan, Utah, has announced the FPS-1 fast photodetector. Designed to measure the temporal pulse shape of lasers or other light sources, the FPS-1 is a high speed photodiode sensor with wide spectral response. The sensor provides a fast 1 ns response time and handles wavelengths from 190nm to 1100nm.

The FPS-1 is compact, easy to use and flexible. Unlike other high speed photodetectors, the sensor provides two modes of operation: the 50 Ohm load measures ns high peak power pulses, while the 10 KOhm load measures longer and lower peak power pulses. Input can be direct beam or from a fiber connection. The sensor operates off a battery or wall cube power supply. ND filters are optionally available to adjust the sensitivity to the power level of the source.
