Olympus Corp. (Center Valley, PA) has introduced a spectral reflectivity measurement system designed for use with lenses, prisms, flat glass, plastics, and electronic components produced by optical manufacturers. The USPM-RU III provides repeatable measurements in seconds, and without the need for backside coating. Spherical, aspherical, and flat surfaces can be accommodated without sample preparation. The system provides reflectivity measurements for wavelengths ranging from 380 - 780nm. Object color can be measured based on spectrophotometric colorimetry determined from prismatic reflectivity.
