摘要： An optical device is configured such that the device includes an inorganic light-transmissive base material and an organic antireflection layer, which is provided on a principal surface of the light-transmissive base material and contains an organosilicon compound, an epoxy group-containing organic compound, and hollow silica, and the light-transmissive base material and at least one of the organosilicon compound and the epoxy group-containing organic compound are covalently bonded to each other. Since dirt, dust, etc. do not adhere to a principal surface of the light-transmissive base material during film formation, the occurrence of a defect in the organic antireflection layer can be prevented. The organic antireflection layer has a larger contact angle than an antireflection layer made of an inorganic material, and therefore has a higher dust-proof effect than an inorganic antireflection layer, and thus, dirt, dust, etc. hardly adhere thereto.
摘要翻译：光学器件被配置为使得该器件包括无机透光基底材料和有机抗反射层，其设置在透光性基材的主表面上并含有有机硅化合物，含环氧基的有机化合物和中空二氧化硅，并且透光性基材和至少一种有机硅化合物和含环氧基的有机化合物彼此共价键合。由于在成膜期间污物，灰尘等不附着在透光性基材的主面上，因此能够防止有机防反射层的缺陷的发生。有机抗反射层的接触角比无机材料的抗反射层大，因此与无机防反射层相比具有更高的防尘效果，因此灰尘，灰尘等难以附着。
