nmos linear image sensors are self-scanning photodiode arrays designed specifically as detectors for multichannel spectroscopy. the scanning circuit is made up of n-channel mos transistors, operates at low power consumption and is easy to handle. each photodiode has a large active area, high sensitivity yet very low noise, delivering a high s/n even at low light levels. s3901/s3904-f series are current-output type nmos linear image sensors with fiber optic windows and feature superior output lin earity and wide dynamic range. the fiber optic windows allow efficient optical coupling to an image device such as image intensifiers suitable for low-light-level detection. the photodiodes of s3901-f series have a height of 2.5 mm and are arrayed in a row at a spacing of 50 ?. the photodiodes of s3 904-f series also have a height of 2.5 mm but are arrayed at a spacing of 25 ?. the photodiodes are available in 2 different pixel quantiti es for each series: 256 (s3901-256f), 512 (s3901-512f, s3904-512f), 1024 (s3904-1024f). features l wide active area pixel pitch: 50 ?
