Xenics has announced the Wildcat+ 640, a new state-of-the-art short-wave infrared (SWIR) camera that pushes the limits of high performance imaging for industrial customers. Xenics is Europe’s leading developer and manufacturer of advanced infrared sensors, cameras and customized imaging systems for the SWIR and the LWIR realm.

Wildcat+ 640 is the new member of the SWIR camera family dedicated to demanding industrial vision applications. With Wildcat+ 640, Xenics is expanding its SWIR camera offering towards industrial implementations such as: process monitoring, industrial machine vision or medical. These high-performance cameras also fit scientific uses.

The Wildcat+ 640 SWIR camera can run at a high speed of 300 Hz in full VGA format with a very low noise of only 45e-. Combined with a large pixel pitch of 20 μm, this gives Wildcat+ 640 a unique ability to work in low light environments.

The ability to detect low SWIR signals is given by the ratio between the pixel surface and the noise floor (also called the ROIC noise). The pixel pitch of Wildcat+ 640 is 20 μm, therefore its surface area is 400 μm2. The noise floor is 45e-, thus the ratio is 8.89. When comparing to products based on 15 μm pitch with the noise of 30e-, their ratio is only 7.5. Wildcat+ 640 offers nearly 20% more capability in working with low SWIR signals.

Marc Larive, Strategic Marketing Manager explains: “This improved performance allows customers to work with a smaller light budget. This can be translated in shorter integration time, or less light power consumption and thus less thermal effect, and finally a cheaper illumination system”.

High speed (300 Hz) and high sensitivity makes Wildcat+ 640 a one-of-a-kind solution for the benefit of highly demanding industrial customers.

With the Wildcat+ 640 SWIR camera, Xenics offers machine vision applications the ultimate combination of high sensitivity, high signal-to-noise and high-speed capability for SWIR detection. In order to comply with industrial standards and requirements, Wildcat+ 640 is proposed with CameraLink™ or a plug-and-play USB3 Vision interface that makes the camera very easy-to-use. Moreover, the GenICam compliance of the camera ensures a straightforward integration in industrial systems.

With Wildcat+ 640, Xenics offers the best performance for machine vision, process monitoring and surveillance applications such as:

  1. Inspection where customers will benefit from high sensitivity to detect small and low contrast defects.
  2. Hyperspectral imagery where customers will benefit from high speed and high signal-to-noise ratio.
  3. Harsh environment vision where customers will benefit from the high sensitivity and the enhanced capability to detect small signals.
