Standard analysis of radiation protection lenses: anti-reflective coating

Radiation-resistant lenses are lenses that block a specific electromagnetic spectrum. Generally speaking, the use of the occasion can be divided into two categories: workplace protection and public protection. This article introduces the anti-reflective coating layer for the standard analysis of radiation protection lenses. Anti-reflective coating In QB2682--2005 performance and quality requirements for anti-reflective coating of coated spectacle lenses, light reflectance and average reflectance are used to test the anti-reflective coating of coated spectacle lenses. In particular, the standard states that all tests are only for the anti-reflective coating in coated spectacle lenses. The specific requirements are as follows: (1) The light reflection ratio p of the single surface of the anti-reflective film lens should be less than 2.5%; (2) If the explicit light reflectance ratio P is wc%), then p should be less than 1.2W(%); (3) If the express average reflectance ratio P- is W(%), P- should be less than 1.2W(%); (4) The difference between the reflectance ratio between the inner edge and the center of the effective aperture on the surface of the lens should be less than o.3% of the center of the IP and the yang edge. In all national standards for spectacle coatings and protective functions, there is no mention of detection methods and quality standards for radiation protection glasses that contain multiple frequency bands. In the next section, we will introduce the inspection standards for radiation protection lenses.。
