The FPD-IG-25 is a fast optical detector for visualizing and measuring the temporal characteristics of laser beams in the spectral range from 900 nm to 1700 nm. It has an InGaAs PIN photodiode and is designed to convert optical signals into electrical signals which are then measured with third party measurement instrumentation such as oscilloscopes or spectrum analyzers for measurement. The FPD-IG-25 has a rise time of 25 psec. Its reverse bias voltage is provided by internal batteries.
