CHEETAH/CHEETAH+
The Cheetah series is based on an in-house developed, temperature stabilized InGaAs detector with a 640 x 512 pixel resolution. The Cheetah 640 camera with single-stage TE-cooled detector offers 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. A visible short-wave infrared (vSWIR) option is available for extension into the visible wavelength band.
NEW: The Cheetah+ series, the advanced version of Cheetah series offers an advanced imaging solution for demanding industrial applications, including wavefront sensing in Free Space Optical communications, hyperspectral imaging, and semiconductor manufacturing with in-line inspection. It comes in both CAM and OEM configurations, achieving remarkable frame rates of 1700 Hz. Both versions are equipped with an in-house developed, temperature-stabilized InGaAs detector that provides a resolution of 640 x 512 pixels.

Description
Cheetah/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/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
Our standard IR software, Xeneth, is included with this camera. Find out more: Software | Xenics
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
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
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
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
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):
- Bobcat 320 and 640
- Cheetah 640 CL
- 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.
