APD Hybrids

035

Avalanche photodiodes (APDs) are particularly well suited for detecting low light levels. They are used in many applications such as rangefinding and Optical Coherence Tomography (OCT). Measurement sensitivity is often limited by the connected electronics. An appropriate amplifier has to be used in order to achieve optimal performance.

The newly developed H series hybrid detectors by LASER COMPONENTS offer users an integrated amplifier in a compact, hermetically sealed housing. The particularly low-noise H1 series comes in a 12-pin TO-8 housing and has a built-in temperature sensor. The maximum bandwidth ranges from 1 MHz to 30 MHz.
The H2/H3/H4/H5 series hybrids are suited for even faster measurements. Here, depending on the model, the bandwidth can range up to 700 MHz. These receivers come in a TO-46 housing. This makes them suitable for devices in which very little space for optical components is available as in handheld rangefinders.

All receivers are available with silicon and InGaAs APDs and covering the ranges 400 to 1100 nm and 1000 to 1650 nm.

With the new ABC550 series we also have a suitable high voltage power supply for each APD receiver available in our delivery program.
