Hamamatsu Corp. has introduced the S9972 and S9973 series front-illuminated full-frame-transfer CCDs, which are suitable for low-light-level detection in applications such as spectrometry, semiconductor inspection and DNA sequencing. The area image sensors offer line-binning operation, which boosts dynamic range typically to 120,000 and increases readout speed, and multiphase-pinned operation, which lowers dark current. They feature low readout noise, 24 x 24-μm pixels with 100% fill factor and a spectral response range of 400 to 1100 nm. The devices are available in active area sizes of 24.6 x 3.0 and 24.6 x 6.0 mm. The S9972 series are uncooled CCD sensors and use a quartz glass window, while the S9973 versions have one-stage thermoelectric cooling and use a sapphire glass window.
