A hot shot for machine vision

Kehl-based Optronis supplies the 25 MP CoaXPress high-speed camera with a higher image rate

At Vision in Stuttgart on November 6-8, Optronis GmbH, the manufacturer of high-speed cameras for industry and science, will be launching its 25 MP high-speed camera with real-time connection. The 25 MP CoaXPress delivers a framerate of 72 images per second at full resolution, thus improving on its predecessor’s performance by more than a third.

The 25 MP CoaXPress provides a high-performance tool for process analysis and fault detection for machine vision in industry. Its predecessor, which came onto the market at the start of the year, was already able to deliver 53 images per second at full resolution. With its 25 MP CoaXPress camera now achieving 72 images per second, Optronis will supply the market with a top performing product with CoaXPress interface from November onward. When the resolution is reduced, the camera’s framerate can be increased to a maximum of 1,688 images per second.

High-speed transmission
The serial transmission concept via CoaXPress allows data to be transmitted at a gross clock rate of up to 6.25 gigabits/sec along one or, if the transmission capacity is upscaled, several 75 ohm coaxial lines. Connected directly to the PC, the 25 MP CoaXPress delivers real-time data for detailed and rapid analysis. As well as its robust design, the camera is also equipped with a particularly light-sensitive sensor to respond to the practical demands of industrial production. Excellent shots can even be achieved by simply illuminating the items for inspection with standard LEDs. This is made possible by the sensor’s 4.5um pixels, which boast a quantum efficiency of 50% at a wavelength of 550nm. Related to its light-sensitive surface and upstream micro lenses, this results in a light sensitivity of 3.4 Volt/lux*sec. With an illuminance of approx. 15 lux – which equates to the minimum level of illumination for a workstation – and without loss of light due to an upstream lens, the sensor is up to 70% saturated.

Standards in product design
“We are now supplying the market with the top performing CoaXPress camera: the 25 MP CoaXPress which has a framerate of 72 fps at full resolution,” says Dr. Bernd Reinke, Product Manager at Optronis. “We are only able to sustain this high level of innovation – from the development of the first marketable CoaXPress for industry and the 4 MP CoaXPress through the high performance 25 MP CoaXPress – by concentrating constantly on maintaining and upgrading standards.” Optronis’ machine vision cameras support the GenIcam standard as well as CameraLink and CoaXPress. Standard industrial lenses are also supported, such as those with an M42 thread as well as market-based Nikon lenses.
“In future, we’ll continue to progress further with the standardization of devices and user-friendly design based on our close cooperation with component manufacturers and customers. In fact, we see the benefits of Optronis cameras in their simplicity – both in their use and in the design of the technology,” adds Reinke.

The 25 MP CoaXPress will be introduced at this year’s Vision. The trade fair takes place in Stuttgart on November 6 – 8. The camera will be on show at the Optronis booth: Stand I 41 in Hall 1.
