OSI Optoelectronics supplies Ultra Low Noise Large Area Photo Detector. OSI Optoelectronics offers diverse types of Photodiodes, Photo detectors, photodiodes, fiber optic receptacles and optical components for x-ray products. Ultra Low Noise Large Area Photo Detector is operated at a higher reverse voltage, up to the maximum allowable value, for achieving even faster response times in nano seconds. The high reverse bias at this point increases the effective electric field across the junction, hence increasing the charge collection time in the depleted region. Ultra Low Noise Large Area Photo Detector is ideal for applications measuring high energy X-rays, X-rays as well as high energy particles such as electrons, alpha rays and heavy ions.
