How does the haze of PS Diffuser plate affect the light transmittance


The haze of PS Diffuser plate has a certain influence on the light transmittance of the material. What kind of influence does it have and what is the haze? Let's have a brief analysis.

How does the haze of PS Diffuser plate affect the light transmittance

Haze, also known as turbidity, can be used to measure the degree of unclear or turbid transparent or translucent materials, which represents the index of characteristic scattering. Haze is caused by the appearance of cloud or turbidity caused by light scattering from the internal or external surface of the material. Simply put, haze is the percentage of the ratio of the scattered luminous flux and the luminous flux of the painful material.


Transmittance and haze are important indicators to measure the transparency of materials. The relationship between them is as follows: Generally speaking, there is an inverse relationship between transmittance and haze, that is, materials with high transmittance have low haze, and vice versa. But the relationship between the two is not always the same, sometimes it has the opposite result. For example, the light transmittance of ground glass is higher, but its haze is also larger. So transmissivity and haze are two optical indexes which are opposite to each other and related to each other.
