![]() It also provides a 2D camera-based reflectivity measurement for structured surfaces. The large measurement spot with homogenous illumination is designed to provide repeatable and representative readings. The spectro2profiler uses a circumferential illumination at 45° with 0° viewing. Different grain types can be easily differentiated - ideal for design and new supplier approval.” As a result, you get objective measures for cell size (mm²) and perceived cell amplitude (P-μm). Christopher Groh, R&D project manager, “The spectro2profiler takes multiple images under different illumination directions to estimate surface curvature. Each setting comes with its own unique algorithm and allows finishers to set pass/fail criteria.Īccording to Dr. It also comes with data analysis capabilities that allow finishers to select from three different settings based on the finish application: coarse paint for powder coated, fine paint for plastic parts or fine-textured paints, and leather-like for injection or slush-molded parts. The spectro2profiler is designed to measure color, gloss and surface structure - three parameters that are said to influence visual quality perception and correlate with what the human eye actually sees. When key automotive OEMs reached out to BYK-Gardner wanting a more standardized way to measure surface texture, the company spent more than three years developing the spectro2profiler. ![]() Some finishers also used microscopes to judge surface structure, but that can be impractical for day to day use. Previously, finishers had to evaluate grain and surface structure visually, but this can lead to imprecise or subjective measurements. The spectro2profiler measures color and gloss as well as analyzes the 3D topography of the surface texture. Credit: BYK-GardnerīYK-Gardner (Geretsried, Germany), additive and instrument supplier for the automotive, paint and plastic industries, offers finishers a tool to objectively evaluate surface structure. The spectro2profiler features a color touchscreen with an icon-based menu.
