NMOS linear image sensor
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. The S3904-2048Q has photodiodes with a height of 2.5 mm, arrayed at a spacing of 25 μm. Quartz glass is the standard window material.
