Falcon 720

Medium Wave Infrared Detector

The Falcon 720 infrared detector uses the latest focal plane technology to provide high-definition infrared images compatible with commercial 720p HDTV signal formats. The 12 μm-pitch focal plane array enables this high-definition detector to be offered in a compact, low-cost, low-power design.

Using the MCT process, the Falcon MWIR detector provides the highest environmental integrity and the superior performance of focal plane detectors.
