Method for determining properties of a coating on a transparent film, method for producing a capacitor film and device for determining properties of a coating on a transparent film

摘要

The invention relates to a method for determining properties of a coating (1) on a transparent film (7) for a capacitor with the use of a structure, comprising: a light source (2), a sensor (3) and a central processing unit ( 4), comprising the following steps: A) moving the transparent film (7) with the coating (1) on a path (10) running between the light source (2) and the sensor (3), B) illuminating the coating on the transparent film (1) by the light source (2), C) detecting the intensity of the transmitted light (5) from the light source (2) by the sensor (3), D) calculating the properties of the coating on the transparent film ( 1) based on the measured intensity of the transmitted light (5) by the process unit (4).
