CHEETAH
The Cheetah series are based on a cooled, in-house developed InGaAs detector with a resolution of 640 x 512 pixels and a 20 µm pixel pitch. Available with single-stage TE-cooled detector and it offers exceptional frame rates of 400 Hz, 800 Hz or 1700 Hz options while the option with three-stage TE-cooled detector supports frame rate of up to 110 Hz. The Cheetah series is offered with a CameraLink interface and is available with a visible short-wave infrared (vSWIR) option for extension into the visible wavelength band.
World’s fastest SWIR Area-scan imaging up to 1700 Hz
Low noise, low dark current
Reliable data transfer via CameraLink
