Infrared Photodiode Detectors with Preamplifiers

Photodiode models with LMSNT preamplifier (-PA) work in photovoltaic mode (with zero bias). Current generated by photodiode is amplified and converted by preamplifier into voltage signal. There is straight correspondence between PD current and resulting output voltage. The signal converted by preamplifier will have the same form, frequency and pulse duration as the photocurrent signal from photodiode.

Photodiode models with LMSNT preamplifier (-PA) are equipped with parabolic reflector and packaged in an aluminum tube for protection and screening. Parabolic reflector protects PD device from damage and increases that part of the radiation that reaches the sensitive area of the photodiode.

For further signal amplification, conversion and synchronous detection of the signals from photodiodes with preamplifiers, we have developed the SDM synchronous detector. SDM synchronous detectors are tuned for optimal operation with LmsXXPD-XX-PA models and make the photodiodes with preamplifier signal measurement easy and convenient. For more information regarding SDM synchronous detector please refer to the SDM page.
