Abstract

Low temperature tests of the G. E. 32x1 and 32x32 InSb CID arrays were carried out to evaluate their potential for use in infrared astronomical instruments. The tests revealed that the arrays could be operated at⪅20°X. with dark currents low enough that integration times of up to 1 hour would be possible. Responsivities up to 1.8 AN for the linear array and 0.4 AN for the area array. at 3.6 microns were observed dropping to 0.9 AN and 1.2 AN respectively at 4.7 microns. The linear array exhibited a troublesome response lag at low flux levels which, limits its usefulness and the area array usefulness will be limited by its higher noise level.
