Transparency of a product is influenced by the absorption and scattering behavior of the specimen. Visually transparency is described by two phenomena: Haze and Clarity. The outstanding precision and reliability of the haze-gard i, as well as its ease of use, have made the haze meter the standard for transparency measurement in the glass, plastic, film and packaging industries.

Transparency Measurement

To guarantee consistent and uniform products, transparency measurement is a need. Depending on the application, the product has to meet different requirements in transmission, haze and clarity. The following article describes how these different effects are visually perceived. In addition, practical hints for measuring and analyzing the transparency of special applications are discussed to achieve reliable measurement results.
