BRIDGEWATER, N.J., Sept. 24, 2009 – The S10141 series back-thinned fast Fourier transform CCDs from Hamamatsu Corp. are suitable for use in spectroscopy applications and for detecting weak light signals from 200 to 1100 nm. The back-thinned structure produces >90% quantum efficiency, two or more times higher than a traditional front-illuminated CCD, the company says, with maximum sensitivity at 660 nm.

To detect weak signals, the sensors have low noise in addition to high sensitivity. Typical readout noise is 4 e- rms, reduced by the built-in one-stage thermoelectric cooler. Thermal efficiency is achieved by the hermetic seal and by cooling only the chip. No moisture or condensation builds up within the sensor package.

The series is available in six formats ranging from 1024 × 122 pixels to 2048 × 506 pixels. With full line binning, pixel binning and area scanning, the rectangular format matches the spectral emission from a grating better than a square format CCD, according to the company. The pixel size is 12 × 12 µm, providing the high resolution required for Raman spectroscopy. Other applications include fluorescence spectrophotometry, inductively coupled plasma, industrial and semiconductor inspection, DNA sequencing and low-light-level detection.

Features include an antireflection-coated sapphire window and a 24-pin dual in-line package. Operating temperature is from -50 to 30 °C.
