Optical Functions Integrated into a Mid-wave Infrared Detector

In the past century, optical functions were integrated onto the visible detectors. Nowadays, most of the visible detectors used for imagery are characterized by a large format, a small pixel pitch and RGB (Red-Green-Blue) filters.

In the infrared bands of interest, the mid-wave infrared range (MWIR) can be divided in two sub-bands. The wavelengths associated to the MWIR blue band are ranging from 3.6 up to 4.2 μm and the red band from 4.6 up to 5.1μm.

LYNRED is developing a new technological brick to integrate two optical functions onto a MWIR focal plane array.
