The S10140-1008 is a back-thinned FFT-CCD image sensor from Hamamatsu, specifically designed for low-light-level detection in scientific applications. The image sensor has an effective pixel size of 12 x 12 µm and is available in image areas ranging from 12.288 (H) x 1.464 (V) mm2 (1024 x 122 pixels) up to a large image area of 24.576 (H) x 6.072 (V) mm2 (2048 x 506 pixels). It delivers greater than 90% quantum efficiency at peak sensitivity wavelength. By using the binning operation, it can be used as a linear image sensor having a long aperture in the direction of the device length making it ideally suited for use in spectrophotometry. It has a line rate of up to 275 lines/s. The sensor has a low noise and low dark signal (MPP mode operation) enabling low-light-level detection, long integration time and a wide dynamic range.
