ֺ Optional attenuators ａnd fiber adapters available
ֺ Battery or wall cube operation
Description
The FPS-1 fast photodetector is a compact easy to use
very fast photodetector with wide spectral response.
It is used to measure the temporal pulse shape of laser pulses.
It has two modes of operation: Into 50Ohm load for ns high peak power pulses ａnd 10kOhm load for longer lower peak power pulses.
In order to adjust the input intensity to the level appropriate for the detector, you may scatter the laser light off of a white matt surface and
back off till the appropriate intensity is reached. Alternatively, or in addition, you may procure the ND attenuators listed below which may
be stacked.
