Avalanche photodiode (APD) module A-cube series

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. APD-Modules Fast and reliable detection of light. In APD modules the driver for operating the avalanche photodiodes is already included. APD modules made by Laser Components APD modules enable very low light levels to be detected quickly and simply in a variety of applications such as laser radar, rangefinding, data transfer or biomedical analysis. The APD modules are based on low-noise avalanche photodiodes made of either silicon or InGaAs with a built-in pre-amplifier and high voltage supply. A temperature compensation function allows the APD to be operated at constant gain across a wide operating temperature range.
