Beyond Visible Machine Vision Cameras

SVS-Vistek, a provider of machine vision technology, has introduced its Beyond Visible line of expanded wavelength cameras. "Leveraging SWIR, UV and Polarized high-sensitivity CMOS sensors from Sony, the new cameras uncover defects that escape conventional cameras or the human eye, among them observing contamination in food, detecting liquid levels through containers, sorting plastics for recycling, inspecting glass, semiconductors and solar panels, and analyzing mechanical stress on reflective or transparent surfaces, among other challenging industrial and scientific applications," said an SVS-Vistek spokesperson.

"Beyond Visible cameras are based on the proven platforms of Mikrotron EXO and FXO series platforms, so they reduce system complexity despite their advanced sensor designs, and each is safely contained within the same rugged, ultra-compact milled aluminum housings to withstand industrial settings," continued the spokesperson. "By introducing Beyond Visible cameras, SVS-Vistek now has one of the most capable and diverse lines of imaging solutions in the machine vision industry."

As standard features all Beyond Visible cameras include the following: region of interest (ROI), logic trigger functions (PLC) with programmable timers, GenTL, sequencers and logic functions and optical and electrical inputs specified with TTL-24V. Beyond Visible cameras from SVS-Vistek are available in three sensor designs and a total of eleven models.

SWIR: Offered in CoaXPress-12 and 10GigE models, Beyond Visible SWIR cameras incorporate the Sony SenSWIR sensor capable of 400nm VIS (visible) to 1700nm SWIR (invisible) spectral sensitivity together with high quantum efficiency. "With an innovative thermal design, the cameras deliver outstanding optical quality and dynamic range results and introduce the possibility of using a single camera for multiple areas of the light spectrum in resolutions up to 1280 x 1024 (1.3 megapixel) at 259 fps," said the spokesperson. The 10GigE model (EXO) provides a large image memory to support fast triggering of image sequences at speeds independent of network load, while the CXP-12 model (FXO) generates minimal heat in the camera housing, even at high speeds.

UV Sensing Cameras: Because of their Sony Pregius UV 2/3" CMOS sensor, Beyond Visible UV cameras reveal defects beyond the spectrum of visible light in the ultraviolet range of 200 to 400nm. Available in CoaXPress-12 and 10GigE interfaces, the cameras deliver resolutions up to 2840 x 2840 (8.1 megapixel) and frame rates of 193 fps, qualifying them for high-speed sorting, fluorescence testing, biological analysis, and the inspection of glass, precious stones, liquids and semiconductors.

Polarized Cameras: Equipped with a Sony Polarsens CMOS low noise sensor incorporating the latest four-directional on-chip polarization filter technology, these cameras measure polarization properties of light that are imperceptible to the human eye. Polarization filters out of glare from a shiny surface, such as polished metal or clear plastic, reducing or removing specular reflection so that defects can be recognized. It is also possible to determine slopes and pitches of surfaces. Resolutions up to 2448 x 2048 (8.1 megapixel) can be realized at frame rates of 43 fps using either GigE or USB3 Vision interfaces.

Like the existing line of SVS-Vistek FXO and EXO cameras, Beyond Visible models' low-power optimized electronics and sensor are tight thermal bonded to the housing, permitting operating temperatures up to 60°C (140° F). An integrated power I/O interface lets simple control tasks be performed with hardware precision via PLC functionality. Without requiring additional drivers, up to four LED lights can be directly controlled by a camera for better identification of substances under inspection.

Because the performance of SVS-Vistek Beyond Visible cameras is only as good as the lens installed, highly specialized C-mountable lenses can be purchased from the company's global distribution network.
