Request InfoHamamatsu CorporationHamamatsu Corp. designed its S7847 series of front-illuminated FFT-CCDs with high IR sensitivity for low-light-level detection in scientific applications, including astronomy and spectrophotometry. The CCD chip is mounted on a four-stage TE cooler with a ΔT of 100 °C. Features include a wide dynamic range, low dark current and a spectral response range of 400 to 1100 nm. Typical readout noise is 6 e2 rms and maximum is 12 e2 rms. A binning operation enhances the signal-to-noise ratio and signal processing speed, and makes the CCDs suitable for use as linear image sensors.
