While not a complete listing of relevant references for our standards and materials, this selected bibliography will help the reader gain knowledge of standards and instrumentation related to our products.…
Previously, we reviewed the first of the basic units we measure: reflectance. We presented a simplified but rigorous definition of the way we quantify the flux reflected from a surface. In…
Color Standards - What Are They? There are a bewildering amount of color standards available, each with a set of properties that will make it very good for some…
The material properties we measure are reflectance and transmittance, or more typically, reflectance factor and transmittance factor. Transmittance and reflectance are the more general measurements, but as we will see…
