The SWIR camera Cheetah+ 640 (Exosens / Xenics) is built for high-speed SWIR imaging and transient event capture in the 900 – 1700 nm band. Its 640 x 512 pixels InGaAs photodiode array with CTIA ROIC (20 μm pitch) supports up to 1700 Hz. Typical applications include wavefront sensing for free-space optical (FSO) communication, hyperspectral imaging, and semiconductor in-line inspection.
The Cheetah+ 640 delivers 1700 Hz full frame over CoaXPress (CXP12). For CameraLink and lower-speed options, see the Cheetah 640.
Overview: The Exosens Cheetah+ 640 provides industry-leading 1700 Hz full-frame SWIR imaging over a reliable CoaXPress interface for wavefront sensing and in-line inspection.
