The use of industrial components increases the operating temperature range from -40 up to 70 degree C. Power over Ethernet is possible for standalone operation. In terms of resolution, Bobcat-640 drives pixel pitch down to 20μm from conventional levels of 25μm, at a high overall resolution of 640×512 pixels. This efficient optical lay-out makes the new camera compatible with a broad range of exchangeable standard C-mount lenses as well as the full range of other lower-cost lenses. With on-board image processing Bobcat-640 operates as a complete IR camera system. Image quality is optimized with on-board signal processing with 14- bit A-to-D conversion.

It is configurable with single non-uniformity correction (NUC), or multiple NUC in Xeneth software. Auto gain, span control as well as trigger in/out are also provided on-board.
The Bobcat-640 spectral response covers 0.9 to 1.7μm, with a VisNIR option available that extends the wavelength realm to the visible (0.5μm). The inhouse developed InGaAs detector is build around Xenics’ CTIA-based Read- Out Integrated circuit (ROIC) operating in high gain or low gain mode. Users can choose to integrate while read or to integrate then read. As a result, Bobcat-640 substantially increases measurement sensitivity by capturing more light and lowering integration times under difficult lighting conditions. With the TE-1 cooled temperature stabilization, Bobcat-640 realizes noise levels of 90e- and low dark current of 1.1.106 e-/s. The high frame rates of up to 100Hz can be further increased in windowing mode.
