Description

Small, high performance InGaAs camera with high image resolution

The Bobcat 640 series is based on an in-house developed, temperature stabilised InGaAs detector with a 640 x 512 pixel resolution.

The Bobcat 640 cameras are offered with high frame rate of 100 Hz. The camera comes with a CameraLink or GigE Vision interface and features low weight and power.

Either for machine vision inspection or scientific research, the compact Bobcat 640 meets requirements of high sensitivity in the SWIR range. We offer a visible enhanced short-wave infrared (vSWIR) option for extended wavelength response into the visible band.

Benefits & Features

  • vSWIR optional
  • Low noise, low dark current
  • CameraLink or GigE Vision interfacing options
  • Versatility with gain modes

Software

Our standard IR software, Xeneth, is included with this camera.

Lenses

Our cameras are compatible with a wide variety of lenses.

We do not manufacture our own lenses, but instead offer a variety of third-party lenses that can be purchased directly from us. We guarantee compatibility for any lenses purchased directly from Xenics.

Frame Grabbers

The Xenics product range includes several products that require a frame grabber card to connect the camera to a PC.

The Euresys GRABLINK full, Imperx VCE-CLEX01 and National Instruments PCIe-1433 frame grabbers are fully integrated in Xeneth and the Xeneth SDK. This means that you can use Xeneth software both to control the camera and to grab images making abstraction of the proprietary frame grabber software.

Other frame grabbers properly integrating the CameraLink and GigE Vision protocol can be used in Xeneth and the Xeneth SDK, however only for command and control of the camera. To grab images you rely on the dedicated software provided by the frame grabber vendors.

Cables & Power Supplies

Xenics develops flexible and modular cameras resulting in a wide variety of camera interfaces. All these interfaces require unique cabling which we keep in stock. Next to interface cables we also offer separate power supplies.

Cases

Xenics ships its infrared cameras all over the world in high-grade custom cases. As our infrared cameras have different sizes, we have several case-types in stock guaranteeing a tight fit. The cases are made of polypropylene which make them very sturdy. They are dustproof, watertight, stackable and can cope with temperatures between -40 °C and 80 °C. In addition they are equipped with an automatic air pressure compensation valve allowing us to ship the cameras all over the globe.

Most of our infrared cameras come with a standard hardshell case upon purchasing.

Filters

A filter can be fitted in the C-mount lens adapter of most Xenics cameras. The following Xenics SWIR cameras have a standard filter holder in the C-mount adapter (only one filter can be mounted and filter has to be 25.4 mm in diameter):

  1. Bobcat 320 and 640
  2. Cheetah 640 CL
  3. Xeva 320 (exceptions: Xeva 2.35)
  4. Lynx

In order to lock the filter in the c-mount adapter, the following filter retainer ring has to be ordered from Xenics, part number: MEC-000614

For a list of suitable filters, please directly contact the filter supplier, Spectrogon, for filter purchases. Please check camera and filter documentation for compatible wavelength ranges.
