A tentative for measure absolute efficiency of some popular Sony CCD by using LISA spectrograph and Kodak CCD as reference. The method is discribed here:
http://www.astrosurf.com/buil/isis/noise/result.htm
The QE reference is a KAF-3200ME CCD (QSI-532 camera).
The measure is a long job and not very easy but the result should not be too wrong...
Note for example blue response improvement given by ICX694 (ICX674) detector.
