Sensor

The back of the mid format ISC9809 package supplies the 41-pin electrical interface to the assembly; on the large format ISC0002 assembly the electrical interface is 28 pins on two sides of the package. An interface description document describes this interface and is provided as part of standard delivery. 

Sensor assembly packaging is available for both mid and large format InGaAs and VisGaAs FPAs. These assemblies consist of one FPA mounted on a thermoelctric cooler (TEC) and are integrated into a FLIR designed dewar, which is powered through pins on the rear side of the assembly. The system f-number is set by the higher level system optical path. The front window of the dewar is BK7A glass and transmits radiation in the 0.9 ?m to 1.7 ?m waveband range; it is canted and coated for minimizing reflections. The window and package opening is sized so as to not vignette the FPA when used with f/1.4 or slower optics. The average window transmittance (at 1.0?m) is greater than 99.5%, with less than 0.1% reflectance at 1.55 ?m.
