New Vision Sensor Launch Makes The Invisible Visible
The effect is similar to the well-known ‘magic ink’: Inks, lacquers, chalks and adhesives enriched with luminescent substances, so-called luminophores, are invisible to the human eye. They only light up when irradiated with ultraviolet light, in different colors depending on the type of substance used. This phenomenon can be used in automation applications to evaluate hidden markings on objects that are invisible to the naked eye – for example, markings after quality tests have been passed, seals on screws with luminescent paint, invisible adhesive beads, or data matrix codes for product identification.
The VISOR UV also offers very comprehensive image processing functions. For the evaluation of the luminescent markings, the SensoPart user has the same extensive detection tools at their disposal as the classic illumination variants (white, red, infrared) of the VISOR Allround series. This opens up a wide range of application possibilities in the areas of object detection, measurement, robotics and code reading.
The UV version of the VISOR is available with two different resolutions (V20: 1440 x 1080 pixels; V50: 2560 x 1936 pixels) and optionally with a monochrome or color chip. The color chip offers the additional option of filtering images according to color channels in order to maximise the contrast between the marker and the background and thus the detection reliability. This is achieved simply by creating a setting in the sensor configuration; separate color filters are no longer required, and application costs are saved.
