Device for checking color of e.g. spectacle lens, has illumination device radiates light optionally with spectral distributions for illuminating glasses, and image pickup device defines spectral distributions as spectral sensitivities

摘要

The device (10) has image pickup device (30) for spectral distributions of luminance data emitted from a radiation surface (16) of illumination device through glass to be checked (12). Analysis module (40) determines local color density values for dye from local transmission values. An image output device (42) outputs a graphic illustration of distribution of local dye density values for dye. Illumination device radiates light optionally with spectral distributions for illuminating glasses. Another image pickup device defines the spectral distributions as spectral sensitivities. An independent claim is included for method for checking the color of glass.
