Stemmer Imaging has introduced the Piranha HS-82-04K series of time delay integration (TDI) linescan cameras with 4096 x 48 or 96 pixel resolution and Cameralink data transfer interface.

This is the latest addition to the Dalsa Piranha HS family of TDI linescan cameras.

The new range offers a maximum line rate of 110kHz and throughput of up to 640MHz and its characteristics can also reduce the number of machine vision components required for many applications, significantly reducing overall costs, according to the company.

The Piranha HS-82-04K offers a selectable ’area mode’ of operation, which facilitates camera alignment and optical focusing.

The cameras are capable of bidirectional scanning and have up to 96 selectable stages, while preventing overexposure with 100x anti-blooming.

Camera configuration is said to be flexible, with the number of Cameralink taps, throughput and line rate controlled through software.

Other programmable features include bit depth, flat field correction, direction control and gain and offset control.

TDI technology increases the integration time available to collect incident light from a moving object compared to other video scanning methods in applications from wafer, PCB and LCD panel inspection to high-end document scanning.

This enhanced sensitivity to low light levels enables reduced lighting levels at conventional speeds or the speed of the target object or inspection web to be increased at conventional light levels.

With less light required, high-frequency AC or standard light-emitting-diode (LED) lighting can be used instead of high-powered, high-cost lighting, such as halogen.

According to the company, this lowers initial system costs and maintenance costs.

The high line rates and sensitivity of the Piranha HS series may also make it possible to reduce the total number of cameras needed in an application.

This would also reduce the number of frame grabbers, lenses, computers and cables required.

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.
