  • Ultracompact Camera

LEUVEN, Belgium, Jan. 30, 2013 — Xenics has launched the Bobcat-640 ultracompact, low-noise, low-dark-current camera equipped for GigE Vision or Camera Link.

The short-wavelength infrared (SWIR) camera with an InGaAs detector is for machine vision and high-temperature process control, as well as science and R&D applications.

It features a GigE Vision or Camera Link interface for easy system integration and fast data transfer. With its form factor of 55 × 55 × 67 mm for the Camera Link version and 55 × 55 × 85 mm for GigE Vision, it operates from −40 to 70 °C. Power over Ethernet is possible for stand-alone operation.

Pixel pitch is 20 μm, with resolution of 640 × 512 pixels. The camera is compatible with a variety of exchangeable standard C-mount lenses as well as with lower-cost lenses, and it features onboard image processing. Image quality is optimized with onboard signal processing with 14-bit analog-to-digital conversion. It is configurable with single or multiple nonuniformity correction in Xeneth software. Auto gain, span control and trigger in/out are also provided onboard.

Spectral response is from 0.9 to 1.7 μm, with an available VIS/NIR option that extends the wavelength realm to the visible (0.5 μm). The InGaAs detector is built around a proprietary CTIA-based readout integrated circuit operating in high- or low-gain mode.

The user can choose to “integrate while read” or “integrate, then read,” increasing measurement sensitivity by capturing more light and lowering integration times under difficult lighting conditions. With thermoelectrically cooled temperature stabilization, noise levels are 90 e. The frame rates of up to 100 Hz can be increased in windowing mode.
