The 2/3in-format Prosilica GX1920 imaging device from Stemmer is suitable for applications such as night-time surveillance, industrial vision and factory automation systems and scientific measurement.

It is claimed to add excellent near-infrared sensitivity and low-light imaging performance in a high-definition (HD) format to the fast 240Mb/s data transmission capability of the GX series of dual GigE Vision cameras from AVT.

This light response in both the infrared and visible regions of the spectrum comes from the new Sony ICX674 CCD sensor with Exview HAD technology.

Available in monochrome and colour versions with 1,936 x 1,456-pixel (2.82-megapixel) resolution and operating at 40fps, the Exview HAD CCD technology provides low noise, anti-blooming and excellent image quality as well as near-infrared and low-light imaging capabilities.

This imaging device can contribute to automotive safety in car-mounted cameras as well as intelligent transport systems.

The GX1920 provides the same sustained maximum data rate of 240Mb/s over conventional Cat5e cables up to 100m long as the other cameras in the Prosilica GX range by using two Gigabit Ethernet ports configured as a Link Aggregation Group.

This configuration allows the use of two cables to double the traditional GigE Vision data transmission rate or a single cable for data transmission at 120Mb/s.

In addition to its speed, resolution and sensitivity, the GX1920 offers smart features to further enhance its imaging versatility.

These include: auto exposure, gain and white balance; flexible binning; region-of-interest readout; stream bytes per second for bandwidth control; asynchronous external trigger and sync input/output; global shutter; recorder and multi-frame acquisition modes; three-axis motorised lens control; and video-type auto-iris.

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.
