Photodetector from Ophir Laser Measurement Group handles 190 to 1100 nm wavelengths

March 16, 2011
The FPS-1 fast photodetector is designed to measure the temporal pulse shape of lasers or other light sources.

The FPS-1 fast photodetector is designed to measure the temporal pulse shape of lasers or other light sources. The sensor provides a 1 ns response time and handles wavelengths from 190 to 1100 nm. Two modes of operation are offered: The 50 Ω load measures nanosecond-high peak power pulses, while the 10 kΩ load measures longer and lower peak power pulses.

Ophir Laser Measurement Group Announces Fast Photodiode Detector for Pulsed Lasers

November 8, 2010 - Logan, UT - Ophir Laser Measurement Group, the global leader in precision laser measurement, today 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 1ns 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 50Ohm load measures ns high peak power pulses, while the 10KOhm 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.
