SVS-Vistek is presenting new versions of its successful, ultra-high-resolution HR camera series at the VISION trade fair. Featuring an enhanced electronic platform, the new industrial cameras support many current sensors and interfaces and thus enable powerful high-end machine vision.
Successful camera series with high resolutions
HR stands for “high resolution”, which is already the guiding principle for SVS-Vistek’s current range of HR industrial cameras. In a single shot, the current top-of-the-line hr120 model captures extremely detailed images with a resolution of up to 122 megapixels, making these cameras an extremely powerful option for applications where every detail counts. According to CMO Andreas Schaarschmidt, several technical features have played a major role in the great success of these cameras in addition to the high resolution offered by HR series: “The data volumes generated at resolutions of 29 to 122 megapixels must also be transported and processed. The current HR series is already feature-rich with state-of-the-art machine vision interfaces such as Dual GigE Vision, 10 GigE Vision, Camera Link and CoaXPress. Added to this is the elaborately designed, massive camera body, which ensures excellent temperature management and allows optional fanless operation on most models even when large sensors are used.”
New electronics and body
SVS-Vistek is building on the success of the HR series, especially in the rapidly growing Asian market, by updating the series to include the latest technology. The newly engineered camera body has been specially developed for ultra-high-resolution sensors. Due to their size, these sensors require high-precision optical alignment. In addition, the high power dissipation of the large sensors places special demands on temperature management as the sensor should ideally have a consistent temperature across its entire surface. The new camera body ensures perfect sensor cooling and is also capable of dissipating waste heat from the new high-performance data interfaces to optimum effect. The company’s engineers simulated the temperature flow in the camera bodies, optimizing it for the new series bodies, which are now being produced in the highest possible quality on X-axis milling machines.
The main underpinnings of the second-generation HR camera come from the electronics platform which has been updated with state-of-the-art technology. “We have made sure that new, fast and high-resolution sensors such as the 120MXSC/M from Canon or the NOIP1SE025KA-GDI from ON Semiconductor can be optimally supported,” says Schaarschmidt. “Depending on the bandwidth of the sensor or the required target frame rate in the application, this new electronics platform is also designed to accommodate all new industrial data interfaces and, with its compatibility with the CoaXPress, Camera Link, GigE Vision and the upcoming and extremely fast 10 GigE Vision standard, covers all requirements that machine vision users have - even in the case of demanding inspection tasks.” Further high-speed interfaces are already in the pipeline.
The new generation also includes mechanical modifications to the HR cameras to improve usability. Extended mounting options make it easier to position the cameras. The built-in multi-channel strobe controller has not been changed, but the upcoming new software release 2.5.1 will substantially improve operations.
“Our current HR series cameras have already proven to be successful in numerous applications, including solar production, large field microscopy, FPD display inspection as well as 3D photogrammetry and surface inspection,” emphasizes Schaarschmidt. “I am convinced that with their revised design and extended technical features the cameras of the new HR series will likewise ensure reliable quality assurance.”
