IMAGE SENSOR
NMOS linear image sensor
S3901-1024Q, S3904-2048Q
Large active area type with 51.2 mm detection length
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 UV sensitivity yet very low noise, delivering a high S/N even at low light levels. The current output type NMOS linear image sensors
also feature excellent output linearity and wide dynamic range. S3901-1024Q uses photodiodes with a height of 2.5 mm, arrayed at a spacing of
50 µm. S3904-2048Q has photodiodes with a height of 2.5 mm, arrayed at a spacing of 25 µm. The photodiode arrays are available in 2 different
pixel quantities, 1024 (S3901-1024Q) and 2048 (S3904-2048Q). Quartz glass is the standard window material.
