The Cheetah cameras are based on a cooled, in-house developed InGaAs detector with a 640 x 512 pixel and 20 µm pixel pitch. The cameras with single-stage TE-cooled detector offer high frame rates of either 400 Hz, 800 Hz or 1700 Hz while the version with three-stage TE-cooled detector offers a frame rate of up to 110 Hz. The cameras come with a CameraLinkTM interface. A visible short-wave infrared (vSWIR) option is available for extension into the visible wavelength band.

Cheetah cameras are the world’s fastest InGaAs cameras with high image resolution. The cameras are equipped with 14-bit ADCs and with C-mount fixture, it allows the use of all standard optical lenses. With its advanced and user-friendly configuration, uniquely combining extreme high-speed, high-resolution, and best sensitivity in a reliable InGaAs array, the Cheetah cameras are perfectly suited for high-speed imaging in the SWIR range for a variety of applications (medical, R&D, wavefront sensing and more).

Software and accessories

Software Software

Our standard IR software, Xeneth, is included with this camera. Find out more: Software | Xenics

Lenses Lenses

Our cameras are compatible with a wide variety of lenses.

We do not manufacture our own lenses, but instead offer a variety of third-party lenses that can be purchased directly from us. We guarantee compatibility for any lenses purchased directly from Xenics.

Frame Grabbers Frame Grabbers

The Xenics product range includes several products that require a frame grabber card to connect the camera to a PC.

The Euresys GRABLINK full, Imperx VCE-CLEX01 and National Instruments PCIe-1433 frame grabbers are fully integrated in Xeneth and the Xeneth SDK. This means that you can use Xeneth software both to control the camera and to grab images, making abstraction of the proprietary frame grabber software.

Other frame grabbers properly integrating the CameraLink and GigE Vision protocol can be used in Xeneth and the Xeneth SDK, however only for command and control of the camera. To grab images you rely on the dedicated software provided by the frame grabber vendors.

Cables & Power Supplies Cables & Power Supplies

Xenics develops flexible and modular cameras resulting in a wide variety of camera interfaces. All these interfaces require unique cabling which we keep in stock. Next to interface cables we also offer separate power supplies.

Cases Cases

Xenics ships its infrared cameras all over the world in high-grade custom cases. As our infrared cameras have different sizes, we have several case-types in stock guaranteeing a tight fit. The cases are made of polypropylene which makes them very sturdy. They are dustproof, watertight, stackable and can cope with temperatures between -40 °C and 80 °C. In addition, they are equipped with an automatic air pressure compensation valve allowing us to ship the cameras all over the globe.

Most of our infrared cameras come with a standard hardshell case upon purchasing

Filter Filter

A filter can be fitted in the C-mount lens adapter of most Xenics cameras. The following Xenics SWIR cameras have a standard filter holder in the C-mount adapter (only one filter can be mounted and filter has to be 25.4 mm in diameter):

  1. Bobcat 320 and 640
  2. Cheetah 640 CL
  3. Xeva 320 (exceptions: Xeva 2.35)
  4. Lynx

In order to lock the filter in the c-mount adapter, the following filter retainer ring has to be ordered from Xenics, part number: MEC-000614

For a list of suitable filters, please directly contact the filter supplier, Spectrogon, for filter purchases. Please check camera and filter documentation for compatible wavelength ranges.
