Stemmer Imaging is offering a camera for applications in laser beam profiling, extended wavelength response coatings or endoscopy, where fibre optics need to be coupled directly to the sensor.

The Stingray camera from Allied Vision Technologies is now available in a version that has no cover glass over the sensor.

This new variant of the Stingray further enhances its flexibility, offering a wide selection of lens-mounts, sensors, case variations, interfaces and cable outputs, which can be configured using building block principles.

For UV imaging in particular, the glass used to cover the sensor can absorb UV rays, inhibiting UV sensitivity.

This can affect a number of applications such as semiconductor/wafer inspection, fluorescence in biology, DNA analysis, astronomy, monitoring of oil spills, monitoring of corona discharge effects in high-voltage electrical transmission lines and imaging of invisible flames such as hydrogen and alcohol.

A sensor can be made more sensitive in the UV region of the spectrum by coating a UV-sensitive phosphor layer directly onto the surface of the sensor.

Although this could be done by removing the cover glass from a conventional camera, it is a very specialist procedure that could result in damage to the sensor, so the availability of cameras without the cover glass is an important consideration.

Sensor performance in the infrared can also be enhanced using specialised IR-sensitive phosphor coatings.

In some cases this can offer a cost-effective alternative to the use of specialised IR sensors such as InGaAs.

The sensor is shipped with a special adhesive foil to protect it against humidity and dust.

This can be removed in a dust-free environment before the sensor is adapted for its particular application.

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.
