Low-light level near infrared camera

Cougar from Xenics

Cougar is the near infrared camera offering lowest noise and highest sensitivity for low-light-level measurements world wide. Cooled by LN2. It 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 noise, low dark current and best response in the SWIR range. All of these features are now combined in one single camera.

High image resolution: 640 x 512 with 20 μm pixel pitch
Ultra-low noise levels (15 e-)
Large format array
Read while integrate feature
Integration up to several hours possible

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 camera 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.
