The S15257-2048 is a back-thinned CCD linear image sensor with an internal electronic shutter for spectrometers. The image sensor uses a resistive gate structure that allows a high-speed transfer. Each pixel has a lengthwise size needed by spectrometers but ensures readout with low image lag. The S15257-2048 features pixels that are long vertically, and have a high aspect ratio of 14 µm × 2500 µm.
