LK39F1 S/N U-1 infrared detector
A multilayered (Hg,Cd)Te detector is described with three infrared bands. Nominal cut-off wavelengths for each band are as follows: (1) Channel 1 - 3 microns, (2) Channel 2 - 6 microns, and (3) Channel 3 - 11 microns. The multilayered detector is mounted in a Honeywell LK39 glass dewar. Accompanying the detector/dewar assembly is a three-channel preamplifier package capable of switching each detector to the single channel input of the HRB Singer Reconfax 4 Mark 4 Infrared Scanner.
