Abstract
An infrared detector assembly (12) of the type used in munitions and night vision systems having an improved focal plane platform (10). The focal plane platform (10) includes an end-cap (32) made from tungsten. Adhesively bonded to end-cap (32) is a ceramic mounting board (34). Ceramic mounting board (34) further comprises gold trace pattern (50) for conducting electrical signals generated by hybrid detector (26) to external control electronics. The improved focal plane platform (10) provides a relatively distortion free, thermally stable mounting platform upon which detector (26) is secured. Premature thermal fatigue failure of the hybrid detector is thereby inhibited.
