Silicon avalanche photodiodes are used in the wavelength range between 250 nm and 1100 nm. The avalanche effect makes them well suited for the detection of extremely weak light intensities.
InGaAs avalanche photodiodes are used to detect light in the spectral range from 1100 nm to 1700 nm. They exhibit significantly lower noise properties than germanium diodes.
APD receivers have an integrated preamplifier and come in a compact, hermetically-sealed housing.
Fast and reliable detection of light. In APD modules the driver for operating the avalanche photodiodes is already included.
Our single photon counting modules are photon counters, sold under the brand name COUNT. They offer phenomenally low dark count rates with the best low noise characteristics & highest quantum efficiency.
These inexpensive block modules can produce voltages up to 1000 V. These digital Bias Controllers are used, in particular, in APD and PMT operation.
