Scattered Transmission • Scattered Transmission is a measurement performed on a material that causes transmitted light to scatter • Solid materials could be: • Plastic films or sheets, e.g., pharmaceutical bottles, plastics, etc. • Fabrics for UV Protection • Sunscreen lotions • Scattered Transmission measurements are performed using the Integrating sphere on the Evolution 600 spectrophotometer Erich Heiden UV/Vis Salesmanager 4
Haze (ASTM D 1003-00) • Haze is the percentage of transmitted light which, when passing through a sample, deviates from the incident beam by forward scattering. Lower haze values imply greater transparency. • Haze is an important property when designing for a transparent application in which observers must be able to see inside or through a part easily and clearly. If a material has a high haze value, it will have decreased transparency – making it more difficult to see inside or behind the sample. A sample with a high haze value will still transmit light, but images may appear foggy or blurred. • Typically, polycarbonate resins have a haze value of about 0.5 to 2.0%. Haze value ranges for other transparent materials are: • Polystyrene: 0.1 to 3.0% • Styrene acrylonitrile: 0.6 to 3.0% • Polymethylmethacrylate: 1.0 to 3.0% • Cellulose acetate: 0.5 to 5.0% • Glass: 0 to 0.17% Erich Heiden UV/Vis Salesmanager 5
