Ophir Spiricon - Sensors

The FPS-10 fast photodetector is designed to measure the temporal behavior of pulsed lasers. The sophisticated high speed circuitry in the FPS-10 has two modes of operation:

x1 gain with 10ns response time for very short pulses with high peak power
x250 gain for longer lower peak power pulses.

The FPS-10 comes with additional filters to adjust the sensitivity to the power level of the source. It also comes with a stand and base. Fiber adapters for the head are also available.
