High resolution small form factor InGaAs camera

Low noise and dark current with fast data transfer over GigE Vision

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 which makes it much easier to integrate in 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. This makes the camera affordable for a wide variety of scientific applications.

We offer two versions of the Bobcat-640-GigE: A SWIR version that is sensitive from 0.9 to 1.7um, and
a VisNIR version, with sensitivity from 0.4 to 1.7 um. Furthermore, the Bobcat-640-GigE has Thermo Electric (TE) stabilization which reduces dark current and optimizes the noise performance.
