| description | To provide an optical member capable of maintaining hydrophilicity for a long period under both environments of an environment where siloxane-based contamination exists under a packaging storage state and an environment where being exposed to outdoor environment, to provide an optical instrument having an excellent antifogging property, and to provide an optical member manufacturing method for manufacturing the optical member.SOLUTION: An optical member includes a substrate and a porous layer on the substrate. The porous layer contains silica particles, and a silanol group contained in the silica particles on a surface of the porous layer is substituted with a functional group of a divalent organic group having a specific a number of atoms and a specific hydrophilic group. In the optical member, a mole ratio of the divalent organic group relative to the silanol group on the surface of the porous layer (divalent organic group/silanol group) is in a range greater than 0.25 and not more than 1.5. An optical instrument includes the optical member. A manufacturing method of an optical member including a substrate and a porous layer on the substrate includes: a coating liquid application process; a drying and curing process; and an organic chain substitution process.SELECTED DRAWING: Figure 1
【課題】梱包保管形態におけるシロキサン系汚染物が存在する環境と屋外暴露環境のいずれにおいても長期間親水性を維持することのできる光学部材を提供する。また、防曇性に優れた光学機器を提供する。さらに、上記の光学部材を製造するための光学部材の製造方法を提供する。【解決手段】基材と、該基材上に多孔質層とを有する光学部材であって、該多孔質層がシリカ粒子を有し、該多孔質層の表面の該シリカ粒子が有するシラノール基が、特定の原子数および特定の親水基を有する２価の有機基が有する官能基により置換されており、該多孔質層の表面におけるシラノール基に対する、該２価の有機基のモル比（２価の有機基／シラノール基）が０．２５より大きく１．５以下の範囲内である光学部材。前記光学部材を有する光学機器。基材と、該基材上に多孔質層とを有する光学部材の製造方法であって、塗工液塗布工程と、乾燥硬化工程と、有機鎖置換工程とを有する。【選択図】図１ |
