The thickness of the optical module is different when measured
The thickness of an optical component is the distance between the front and back surfaces of the component. It is typically measured in millimeters (mm). TTV defines the maximum physical variation in thickness of a parallel window or concentric spherical optic, but can be measured optically. The most preferred technique for a specific application or process, depends upon the film type, the thickness of. ABSTRACT: We measure the thickness of the encapsulation layers in photovoltaic modules using scanning acoustic microscopy and optical microscopic imaging. 5 points on 150 mm, 9 points on 200 mm, 13 on 300 mm wafers).
