Required CCD temperature stability
I have been refining the system specification for introduction of a new
CCD camera. I have been considering a back-illuminated SITe chip, cooled
at around -100 deg. I have been wondering what degree of temparature
stability is required, in order to obtain a high degree of photometric
stability frequently discussed in this forum. My chief concern is the
effect of possible fringes, variabile according to temparature, in red
pathbands. Could someone suggest?
Regards,
