[Test Case] Strength Distribution of Plastic Lens Coating for Glasses

Detailed explanation of the test results for the strength distribution in the depth direction from the lens surface to the substrate.

We will introduce a case study evaluating commercially available coated eyeglass lenses. By investigating the actual strength distribution inside, results were obtained indicating that "the surface inorganic layer is an anti-reflective (AR) coating, and the intermediate layer can be identified as a hard coat." 【Case Overview】 ■ Purpose - To investigate the actual strength distribution inside the surface multilayer coatings of two types of commercially available eyeglass lenses. ■ Evaluation - Upon magnifying the surface inorganic layer, it is evident that it is a multilayer film. - From the erosion rate distribution, it can be determined that the surface design (layer composition according to purpose) differs, among other findings. *For more details, please refer to the PDF document or feel free to contact us.
