In general, MgF₂, which is a low-reflective coating material, has a refractive index of 1.38. The refractive index of a single layer of MgF₂ is not sufficient for industrial applications. In this study, an anti-reflection MgF₂ coating film with low reflectivity and high wear resistance was synthesized to be used as a single layer with a TEOS binder. The prepared anti-reflection coating film was coated in the form of nanoparticles on a curvature lens having an aspherical surface coefficient by spin coating, and the correlation with optical properties was confirmed through particle size measurement. The MgF₂ nanoparticle AR coating film was characterized by LDPSA, UV-Vis, SEM and ellipsometry. Mechanical and optical properties were confirmed with a minimum reflectance of 0.1% or less and a low refractive index of 1.24–1.25.

开发 MgF2 纳米粒子以改进非球面透镜上的抗反射涂层

通常，作为低反射涂层材料的MgF ₂具有1.38的折射率。_{单层MgF 2}的折射率不足以用于工业应用。在这项研究中，合成了一种具有低反射率和高耐磨性的抗反射 MgF ₂涂层膜，与 TEOS 粘合剂一起用作单层。通过旋涂将制备的抗反射涂层膜以纳米颗粒的形式涂覆在具有非球面系数的曲率透镜上，并通过粒度测量确认与光学性质的相关性。MgF ₂采用 LDPSA、UV-Vis、SEM 和椭偏仪对纳米粒子增透膜进行表征。机械和光学性能经证实具有 0.1% 或更低的最小反射率和 1.24-1.25 的低折射率。
