Silicon avalanche photodiodes are used in the wavelength range between 250 nm and 1100 nm. The avalanche effect of these photodiodes makes them well suited for the detection of extremely weak light intensities.
Si-APD are suitable for the spectral range from 255 nm to 1100 nm.
The SAP-series silicon avalanche photodiodes are primarily used in photon counting. This series features highest efficiency and lowest dark current rates.
The detector was developed specifically for (bio)medical applications in which the smallest signals in the short-wave UV/blue spectral range have to be detected.
