UltraScan VIS (US VIS) provides exceptional precision for opaque, translucent, transparent, dark, and highly saturated samples. Using diffuse/8° geometry with automated specular control, it measures reflected and transmitted color as well as haze in compliance with CIE, ASTM, and USP standards. Its outstanding long-term stability ensures confidence that color differences reflect true product changes—not instrument variability.
