The UltraScan VIS easily measures both reflected and transmitted colour as well as transmission haze and meets CIE, ASTM and USP guidelines for accurate colour measurement. UltraScan VIS uses diffuse/8° geometry with automated specular component inclusion/exclusion. For transmission measurement, the use of a robust CIE-conforming sphere instrument (TTRAN Total Transmission mode) effectively negates the effects of minor scattering typically found in transparent samples.
Because of its exceptional inter-instrument agreement and long-term stability, you can be confident that differences between measurements are due to product colour changes, not instrument variability. Materials on the borderline of accepted tolerances will not be unnecessarily rejected.
