APD Modules

APD modules enable very low light levels to be detected quickly and simply in a variety of applications such as laser radar, range finding, data transfer or biomedical analysis.

In addition to the wide range of avalanche photodiodes already offered, Laser Components introduces their new line of APD modules. With the help of APD modules, even the smallest amount of light can be detected quickly and reliably. This quality is essential in data transmission, laser radars, rangefinders, or biomedical systems.

The new APD modules are built with a low-noise silicon or InGaAs avalanche photodiode with a preamplifier and an integrated high voltage power supply. The built-in temperature compensation facilitates extremely reliable operation of this module at a constant gain across a wide temperature range.

The built-in InGaAs detector has a diameter of 200 µm, which makes it possible to measure in the spectral range from 1000 nm to 1650 nm. The silicon versions from 400 nm to 1100 nm are available with integrated APDs of D = 500 µm and D = 1.5 mm. They offer a bandwidth from DC to 25 MHz.

Because all the components are stored in a small, shielded metal housing (approx. 75 x 56 x 26 mm), only a standard 12 V DC power supply is required for operation. This makes the use of an APD and the detection of even the smallest amount of light extremely easy.
