The S11156-2048-02 is back-thinned CCD linear image sensors with an internal electronic shutter for spectrometers. This image sensor uses a resistive gate structure that allows high-speed transfer. The pixel has a lengthwise size needed by spectrometers but ensures readout with low image lag. Image lag on these products is reduced by nearly a magnitude of 10 as compared to the previous product (S11156-2048-01). Note that the transmission of long wavelengths in the dead layer covering the horizontal shift register was reduced compared to previous product.
