Working Principle
The MG100 functions by projecting a high-intensity LED light through radiographic film mounted on its viewing screen. As the light diffuses through the acrylic surface, users can visually inspect the film for defects and flaws. The bright, evenly distributed illumination enables users to assess film density and compliance with relevant inspection standards.
