ABSTRACT:
An infrared (IR) microlens array has a plurality of microlenses (12) aligned with respective IR detector array pixels (6) to focus incoming IR radiation onto the pixels (6) to improve the efficiency of IR detection, and a gas molecule getter grating (14) inside a vacuum-sealed Dewar assembly that houses the detector array (4) increases the surface area of the getter (15) to improve the efficiency of removing residual gas molecules from the Dewar assembly.
