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.

Company information
Amid the significant trend of paradigm shifts, through creativity-driven research and development, we aim to propose new surprises—values and technologies, as well as next-level efficiency and quality—to our society, spreading all these surprises to the world and creating a vast network of "monozukuri" (manufacturing) and "kotozukuri" (value creation). We aspire to expand a network of manufacturing that encompasses the world, starting from Nagaoka, a city representing Niigata, a region known for its industrial development.
