Coatings and plastics that contain special effect pigments show angular-dependent reflection characteristics. Interference pigments, for instance, exhibit a color impression (“appearance”) that changes with the directions of illumination and obse

The basis for the description of diffuse reflecting materials is the concept of the radiance factor ?, or as a quite similar depiction, the bidirectional reflectance distribution function fr. Both characterizations use the concept of the perfectly re

We describe a new, easy-to-use reagent, Cyto-Chex (Streck Laboratories, Omaha, Neb), that preserves fresh whole blood in a non-cross-linking, nonformalin manner. Target values assigned to fresh blood were essentially met after preservation and storag

A comparison between the absolute gonioreflectometric scales at the Helsinki University of Technology (TKK) and the Physikalisch-Technische Bundesanstalt (PTB) has been accomplished. Six different reflection standards were measured for their 0:45 spe
