Photodiode MID-IR PD 25-10-PA

Photodiodes PD 25-10 are designed for detecting radiation in the Mid-Infrared spectral range from 1000 to 2500 nm. The preamplifier (-PA) works in photovoltaic mode (with zero bias). The current generated by the photodiode is amplified and converted by the preamplifier into a voltage signal. There is linear correspondence between PD current and resulting output voltage. The signal converted by the preamplifier will have the same form, frequency and pulse duration as the photocurrent signal from photodiode. The pre-amplified photodiodes are equipped with a parabolic reflector and packaged in an aluminum tube for protection and screening.
