Method and device to measure the optical transmission factor of a tinted glass panel by reflection |
摘要 |
In a method and a device for determining the optical transmission factor of a glass panel by identification transmits an incident electromagnetic radiation towards the glass panel and the intensity of the reflected radiation is detected and measured. The reflection coefficient of the panel is compared with reflection coefficient reference values representing the transmission factor of tinted glass reference panels to determine the optical transmission factor of the panel examined.
