The S3904-512F is an NMOS linear image sensor designed for multichannel spectrophotometry applications. It features a current-output type configuration with a fiber optic window, which enhances optical coupling to image devices, making it suitable for low-light-level detection. The sensor has a pixel height of 2.5 mm and a pixel pitch of 25 µm, allowing for a dense array of photodiodes that provide high sensitivity and low noise, resulting in a favorable signal-to-noise ratio even under low light conditions. This model operates with a maximum power consumption of 1 mW and supports a wide dynamic range due to its low dark current and high saturation charge, enabling long integration times at room temperature. The S3904-512F also offers excellent output linearity and spatial uniformity in sensitivity, making it a reliable choice for precise spectroscopic measurements. The device is compatible with CMOS logic for start and clock pulses, facilitating integration into various electronic systems.
NMOS linear image sensors with fiber optic windows
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. S3904-512F is a current-output type NMOS linear image sensor with a fiber optic window and features superior output linearity and wide dynamic range. The fiber optic window allows efficient optical coupling to an image device such as image intensifiers suitable for low-light-level detection. The photodiode of S3904-512F has a height of 2.5 mm and is arrayed in a row at a spacing of 25 μm.
