What is the difference between regular transmission and diffuse transmission?
1. Regular transmission
The phenomenon that light deflects through a material with a smooth surface and a uniform medium and then deflects at the same angle is called regular transmission.
2. Diffuse transmission
The light passes through a material with a rough surface or an uneven medium, the transmitted light will be scattered in many directions because the light will be refracted at different angles on the rough materials' surface and at the junction of the uneven medium, this phenomenon is known as diffuse transmission.
-
One key optical effect of diffuse transmission is wide-angle scattering, which results in haze. Haze occurs when light is scattered at large angles, leading to a milky or cloudy appearance. This phenomenon is particularly relevant in the evaluation of transparent plastics, films, and coatings, where excessive haze can impact both visual aesthetics and functional performance.
-
Another effect associated with diffuse transmission is narrow-angle scattering, which affects clarity. Clarity describes how well fine details can be seen through a transparent material. When light is deflected at small angles, it results in a distortion of object outlines, making fine details harder to recognize. Unlike haze, clarity is highly dependent on the distance between the observed object and the material—the farther the object, the greater the distortion. This property is particularly important for automotive windshields, display screens, and high-precision optical materials, where maintaining high clarity ensures optimal visibility and sharp image reproduction.
By understanding the principles and difference of regular transmission and diffuse transmission, industries can better select materials with appropriate optical properties. Instruments such as a haze meter or an optical density meter help quantify these effects, ensuring that transparent materials meet specific quality standards.
