Unlike reflection haze - which is caused by a microscopic surface structure which slightly changes the direction of a reflected light causing a bloom adjacent to the specular (gloss) angle - transmission haze occurs when light passes through a transparent material and creates an unfocused or blurry appearance of the objects behind it.
Inconsistent transmission haze can be problematic in a number of materials and applications. Some industries regulate the haze of a product and can be essential to the product's production. The only universal solution is to gain a true understanding of all the variables involved in the process.
Primary Topics:
- Defining haze and hazen
- Standard transmission measurement geometries
- Measurement conditions and adjustments
- Haze and opacity measurements
Presenter:
Stephen Dolph
Application Engineer: Color and Appearance; Konica Minolta Sensing Americas, Inc.
Stephen has a background in mechanical engineering & physics. He was a research and teaching assistant. In recent years, he was engaged in industrial image engineering. He has broad experience in spectrophotometers, paint formulation and recipe prediction. Among other topics, Stephen will discuss defining haze and hazen, and solutions for Standard Transmission Measurement Geometries Opacity Measurement, and ASTM D1003 procedures.
