Stemmer Imaging has introduced a compact, uncooled, near-infrared (NIR) camera for inspection and quality control applications in the semiconductor, waste sorting and food inspection industries.

The new Xenics Bobcat-1.7-320 incorporates an embedded digital signal processor for real-time image processing.

The camera uses both subsurface NIR inspection and thermal imaging capabilities.

NIR imaging also has applications for online quality control, while thermal imaging provides quality control for thermal processes and thermography between 300C and 800C.

The highly sensitive InGaAs detector is suitable for low-light levels and does not require cooling, meaning that it has a low power consumption.

If additional SWIR illumination is required, the Bobcat can be used in conjunction with light sources such as an eye-safe 1.55um laser.

Thanks to its built-in digital signal processing, PC connection via standard Ethernet or optional Cameralink connections and its compact size, the Bobcat can be used in restrictive and challenging industrial environments.

Standard C-Mount lenses and protective camera housings can be used.

The Bobcat is supplied with a graphical user interface, which facilitates the control of the camera and the acquisition of images.

Images and movies can be saved in various file formats.

NIR imaging provides information not available from visible spectrum imaging, according to the company.

This can range from sugar content in fruit to low-level photon emissions caused by semiconductor grid defects and absorption by various plastic materials.

NIR imaging also enables features below the surface of an object to be viewed, allowing internal defects to be imaged and opening the possibility of inspecting product through, for example, plastic packaging.

For thermal imaging applications, NIR radiation will pass through glass for imaging, whereas glass is opaque to low-wavelength infrared (LWIR) cameras.

STEMMER IMAGING is Europe’s largest imaging technology provider with headquarters in Germany and subsidiaries in the United Kingdom, France and Switzerland.

Image processing or Machine Vision is used in many different application areas – such as industrial automation, medical imaging, security and traffic technology – as a powerful and cost effective way of implementing automatic quality assurance. Even at high speeds and with stringent accuracy requirements, image processing allows 100% monitoring and thus strengthens the competitive edge of those companies using it.

STEMMER IMAGING customers have access to a wide variety of imaging products from the worlds leading manufacturers. These manufacturers represent the cutting edge of vision technology which is something that is unique in Europe. STEMMER IMAGING are the developers of the world’s leading image processing software platform, Common Vision Blox, and as a manufacturer of customer-specific products, we have a full range of in-house expertise to draw on, allowing us to supply the best possible service to our customers when choosing an imaging solution. STEMMER IMAGING does not produce turn-key solutions – instead, using our close partnerships with a large number of experienced system integrators, we can provide expert technical know-how for the planning, integration and realisation of complete solutions.
