formerly Topcon Technohouse Corporation Optical Measurement Solutions for Next-Generation Mobility Quantifying the Optical Quality of Brand Design One Metric Across Development, Quality Control, and Production Ensuring Consistent Lighting Quality at Every Stage

As lighting designs become increasingly complex, visual inspection alone is no longer enough. Our optical measurement solutions visualize everything from luminance and chromaticity to subtle color variations with exceptional accuracy. Evaluating automotive interior and exterior lighting requires more than measuring brightness and color. It requires measurements across a wide luminance range, from nighttime to daylight conditions, as well as evaluation across viewing angles and correlation with human visual perception. * Design target and measured values do not match, with no clear cause * Chromaticity...
