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.
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.
The SUR-Series is based on a silicon “reach-through” structure with high sensitivity in the DUV/UV wavelength range. The benefit of the SUR-Series is an extremely high sensitivity and low noise performance operating in the blue wavelength range and superior to any similar detector available presently on the market.
An important additional advantage of the new reach-through APD is its unmatched noise and sensitivity performance over the widest commercially available wavelength range, from 255 nm to 1000 nm.
