Cheetah Series
World’s fastest InGaAs camera with high image resolution
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.
Benefits & Features
• World’s fastest SWIR areascan imaging up to 1700 Hz
• vSWIR optional
• Low dark current
• Reliable data transfer via CameraLink
