360° Panomorph Lens Series

Digital Imaging Colorimeter (DIC)

    This system contains a software, a calibrated DSLR with a wide-angle lens. It is readily used for the measurements of distributions of luminances and color coordinates, as well as analysis of further parameters. For requirements of illuminant evaluation, glare evaluation, lighting design, and colorimetric distribution, it provides an accurate, fast, and mass measurement capability.

Functions

˙Measurements of distributions of luminances and

    color coordinates

˙Color and flat field calibrations with respect to

    DSLR settings
