What is haze and Total transmittance

Latest company news about What is haze and Total transmittance

Haze, English name haze, is the percentage of the transmitted light intensity deviating from the incident angle by more than 2.5 degrees to the total transmitted light intensity. The greater the haze, the lower the gloss and transparency of the film, especially the imaging degree. It is an important parameter for the optical transparency of transparent or translucent materials (plastic plate, sheet, plastic film, flat glass). According to the national standard, for each sample, the haze is calculated as a percentage.

 

Total transmittance is a physical term that indicates the ability of light to pass through a medium. It is the percentage of the luminous flux passing through a transparent or translucent body and its incident luminous flux. When the incident light intensity I0 is constant, the greater the intensity ia of the medium absorbing light, the smaller the intensity it of the transmitted light. It / I0 is used to represent the ability of light to pass through the medium, which is called transmittance. It is expressed in T, that is, t = it / I0
