APD Receivers

APDs with matched, integrated pre-amplifier in compact hermetic packages.

All receivers are available with Si or InGaAs APDs.

Our Receivers

The performance of an APD in a specific application is often limited by the pre-amplifier, therefore the pre-amplifier needs to be chosen and implemented with great care in order to achieve the best possible signal-to-noise ratio. Our H-series receivers offer the user an APD with matched, integrated pre-amplifier in a compact, hermetic package.

All the receivers listed below are available with silicon* or InGaAs**-APDs and are therefore suitable for the wavelength ranges 400 – 1100 nm and 1000 – 1650 nm respectively.

* (SAE-, SAR-, SAT-Series)

** (IAG-Series)


H0 Series

The H0 series includes a Silicon or InGaAs APD with an optimized low noise hybrid preamplifier for the use in laser range finding, LIDAR, medical and analytical applications. Housed in a modified 5 pin TO-46 package they offer bandwidths up to 1 GHz and a single ended output. Higher bandwidth can be achieved by further lowering the feedback resistor values.


The ultra low-noise H1-series is supplied in a 12-pin TO-8 package and features a built-in temperature sensor to allow temperature compensation. The maximum bandwidth is 1 MHz to 30 MHz depending on the version.

H2 / H3 / H4 / H5 Series

The H2/H3/H4/H5 series of receivers is designed for even faster applications, with bandwidths of to 700 MHz offered. These receivers are supplied in a compact TO-46 package.

High Voltage Modules for APD

With the inexpensive block modules from LASER COMPONENTS it is very easy to supply voltages up to several 1,000 V.


about Avalanche Photodiodes

Semiconductor Materials

Similar to photomultipliers, avalanche photodiodes are used to detect extremely weak light intensities.

Si APDs are used in the wavelength range from 250 to 1100 nm, and InGaAs is used as semiconductor material in APDs for the wavelength range from 1100 to 1700 nm.
