CCD area image sensor
S7847 series
High IR sensitivity, four-stage TE-cooled, front-illuminated FFT-CCDs
S7847 series is a family of FFT-CCD image sensors specifically designed for low-light-level detection in scientific applications. By using the
binning operation, S7847 series can be used as a linear image sensor having a long aperture in the direction of the device length. This makes
S7847 series ideally suited for use in spectrophotometry. The binning operation offers significant improvement in S/N and signal processing
speed compared with conventional methods by which signals are digitally added by an external circuit. S7847 series also features low noise and
low dark signal (MPP mode operation). These enable low-light-level detection and long integration time, thus achieving a wide dynamic range.
S7847 series has a pixel size of 24 × 24 µm and is available in active area of 24.576 (H) × 2.976 (V) and 24.576 (H) × 6.048 (V) mm.
A four-stage Peltier element is built into the same package for thermoelectric cooling. At room temperature operation, the device can be cooled
down to -70 ˚C with using forced air cooling. In addition, since both the CCD chip and Peltier element are hermetically sealed, no dry air is
required, thus allowing easy handling.
