NMOS linear image sensor
S3901/S3904 series
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. NMOS linear image sensors also offer excellent output
linearity and wide dynamic range.
The photodiodes of S3901 series have a height of 2.5 mm and are arrayed in a row at a spacing of 50 µm. The photodiodes of S3904 series also
have a height of 2.5 mm but are arrayed at a spacing of 25 µm. The photodiodes are available in 3 different pixel quantities for each series: 128
(S3901-128Q), 256 (S3901-256Q, S3904-256Q), 512 (S3901-512Q, S3904-512Q) and 1024 (S3904-1024Q). Quartz glass is the standard window
material.
