The Cheetah 640 series is based on a cooled, in-house developed 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. The camera comes with a CameraLink interface.
A visible short-wave infrared (vSWIR) option is available for extension into the visible wavelength band.

Camera Link offers high data rates, deterministic timing and very direct access to the image sensor. Our high resolution industrial cameras with Camera Link provide a wide range of core features:
Camera Link permits settings and operating modes that are not available with other interfaces:
Having superb image quality, the all-new IC-X25B-CL provides the best performance-for-value ratio of all of ISVI’s new compact cameras. Using its Full Configuration Camera Link interface it achieves a frame rate of 30Hz. Its compact size and wide selection of standard lens mounts makes it a popular choice for users requiring a high-resolution camera but do not need the high frame rates of our CXP cameras.
Key Features:
EXO Camera Link models let you maintain the existing and proven infrastructure for years to come, while making use of the newest range of image sensors. The serialized interface has gained wide popularity and acceptance thanks to its high bandwidth. The EXO series was the first Camera Link model to include features such as 4IO strobe controller and LUT.
The high resolution SHR series offers outstanding image quality. This is made possible by the excellent physical characteristics of large pixels in large format sensors. The thermally highly optimized housing guarantees highest optical precision. The large M72 lens mount (FFD 19,55) can be adapted to any lens.
Highlights of the SHR series (some features only on some models)
10 GigE interface
The economical high-performance 10 GigE interface offers high data transfer speeds of up to 1.1 GB/s for these large images. A special frame grabber is not required.
