The RS6780 infrared camera systems have been developed by Teledyne FLIR to meet the needs of the commercial R&D and test range users. The RS6780 has an InSb detector to cover the MWIR band, and it uses a 640 x 512 array with 15μm pixel pitch.
Typical direct injection ROIC designs exhibit a non-linear response when the signal drops below 10% of well-fill. FLIR ROICs provides a linear response even at very low signal levels. This results in an increased linear dynamic range, much better NUC performance at low signal levels and makes it easier to perform a user calibration of the camera.

The cameras support a selection of standard and user-defined color palettes for the standard video output. Ruggedized Construction The RS6780 camera is packaged as a sealed enclosure that can maintain a dry nitrogen gas purge. Digital Detail Enhancement (DDE) DDE is an analog video AGC mode that provides a significant improvement to scene detail and contrast.
➢ The camera is a precision optical instrument and should not be exposed to excessive shock and/or vibration. Refer to Chapter 7 for detailed environmental requirements. ➢ The camera contains static-sensitive electronics and should be handled appropriately.
