CCD linear image sensor
S15257-2048
Back-thinned CCD image sensors with electronic shutter function
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.
Features
-Built-in electronic shutter
-High sensitivity from the ultraviolet region
(spectral response range: 200 to 1000 nm)
-Readout speed: 10 MHz max.
-Image lag: 0.1% typ.
-Light-shielded CCD horizontal shift registers
