Horiba Scientific has introduced QExtra Technology for back-illuminated deep depleted CCD detectors, an anti-reflective multilayer coating that is aimed at significantly improving the quantum efficiency over a broad spectral range while minimising the undesirable etaloning effects.
The company says that, with QExtra Technology there is up to a 50 per cent improvement in the quantum efficiency compared with the basic BIDD CCDs currently on the market, and it is available in both thermoelectrically cooled and liquid Nitrogen-cooled CCDs.
This increase in sensitivity offered by QExtra Technology makes Horiba Scientific BIDD CCDs the ideal scientific detector for luminescence and Raman spectroscopy applications, the company says.
