Dark Current and Influence of Target Emissivity

For very advanced scientific applications with extremely low light levels, Xenics has developed the Cougar camera. The Cougar camera is based on Xenics’ 640 × 512 pixel InGaAs detector array (with 20 μm pixel pitch), combined with a completely new in-house-developed Read Out Integrated Circuit (ROIC), based on a low-noise SFD topology rather than a standard CTIA pixel interface.
