Bobcat 640 - Digital Infrared Camera System

With superior image quality, the Bobcat-640-GigE is available as a complete digital infrared camera system with on-board image processing. The Bobcat-640-GigE comes with an industry-standard GigE Vision interface making it much easier to integrate into your own set-up.

With the Bobcat-640-GigE SWIR camera you can look through glass, so standard available C-Mount lenses and protective camera housings can be used. There are two versions of the Bobcat-640-GigE available: A SWIR version sensitive from 0.9 to 1.7 µm, and a VisNIR version with sensitivity from 0.4 to 1.7 µm. The Bobcat-640-GigE has Thermo Electric (TE) stabilization which reduces dark current and optimizes the noise performance.

Also available is the ultra-compact Bobcat-640-CL, which meets the needs of machine vision system designers who require high sensitivity in the SWIR range for specialized quality inspection and high temperature process control. The Bobcat-640-CL is perfectly suited for high speed imaging at full 640x512 resolution with high frame rates up to 100 Hz. The camera comes with an industry-standard CameraLink interface for data transfer at full frame rate. The frame rate can be even further increased in windowing mode. Several compatible frame grabbers for the CamerLink interface are available.

The Bobcat-640-CL comes as a complete camera with on-board image processing and Thermo Electric stabilization for low dark current and optimized noise performance, all resulting in superior image quality. A VisNIR option extends the wavelength into the visible realm for best sensitivity in low-light applications.
