Cougar-640

LN2 cooled high resolution SWIR camera

Designed to have the lowest noise and highest sensitivity for low-light-level measurements

 

The Cougar-640 excels in performance for any R&D spectroscopy or semiconductor failure analysis task. These demanding applications, where very low light levels need to  be measured, require cameras with low dark current, low noise and best response in the SWIR range. All of these features are now combined in one single camera.

The in-house developed InGaAs detector of the Cougar-640 is optimized for 77K operation, using Liquid Nitrogen (LN2) cooling and is based on a SFD (Source Follower per Detector) read-out topology for ultra-low noise levels ever seen (15 e-). Integration time of several hours is possible with the RWI (Read While Integrate) feature with nondestructive readout and very low dark current of less than 10e-/second.

The Cougar-640 features a high image resolution of 640 x 512 with a 20 μm pixel pitch and full 24 bit ADC. Camera interfacing is provided via standard CameraLink for ease of integration.
