Infrared LEDs and photodiodes for 1000-5000 nm spectral range based on InAs-GaSb-InP heterostructures and optoelectronic devices utilizing LEDs and photodiodes – a new base for sensors and analysers with low power consumption and fast response time.

SDM Synchronous Detector

Datasheet 

APPLICATION

SDM synchronous detector measures the voltage signal from the output of photodiode preamplifier and converts it to the DC voltage signal proportional to amplitude of voltage from input.

FEATURES

• Basic version includes one detection channel. Number of independent detection channels can be increased to two or three channels on request.
• Built-in power supply for preamplifier(s).
• Possibility of input polarity inversion using the appropriate jumper. In case of wrong polarity connection from photodiode preamplifier one can simply switch the input polarity inversion jumper.
