NIR320 OEM InGaAs Near-Infrared Camera Specification

Lumitron introduces the fully customizable OEM Indium Gallium Arsenide (InGaAs) Near-Infrared Camera Module. This product includes a baseline FPA and ECS320A camera electronics. In addition to the baseline components, the customer may select an optic (f #, focal length, motorized / manual focus, multiple FOV, etc), select a housing, select the I/O requirements and select their own product name (since this is your product). This camera will have your company’s look and feel including any labeling that you desire. These options can be selected from our existing solutions, can be fully developed by the customer and integrated into the product or designed to your requirements by our engineering staff. Lumitron will also consider other “320-class” FPAs for the camera module.

The Lumitron ECS320A Embeddable Camera Electronics System provides the foundation of the camera module. The ECS320A is comprised of three primary printed circuit board assemblies (each 2 inches x 2 inches). The ECS320A architecture includes an FPA-specific FPA Support Electronic PCB, a universal Camera Controller PCB and a universal Camera Support Electronic PCB. The ECS320A provides high-functionality imaging capabilities which include: FPA clocking / biasing / power generation, FPA analog video conditioning, FPA video analog-to-digital conversion (14-Bit), FPA non-uniformity correction (two point with ambient temperature compensation and run-time refresh), defective pixel replacement, dual 14-Bit in / 16-Bit out intensity transformation table (contrast enhancement / radiometric transforms), automatic gain and level control (linear or histogram equalization), interpolated horizontal remapping, display freeze and 2x zoom, standard format analog video generation (NTSC or PAL), 15 color full-screen bit-mapped symbology overlay onto video output, thermoelectric cooler control, calibration flag controller, and input power conditioning / regulation. An application specific Panel I/O PCB connects the ECS320A primary electronics to the external environment.
