Because glass has high hardness and chemical resistance, it is widely used in living and industrial fields. However, depending on the amount of water vapor in the air, the glass surface becomes cloudy, which causes visibility problems. Recently, dots have been formed on the glass surface by processing using a femtosecond laser. As a result, it has been reported that superhydrophilicity is imparted to the glass surface and the transmittance is improved. We investigated the processing conditions to achieve superhydrophilicity by forming a periodic structure on the glass surface by processing using a femtosecond laser. In this study, we investigated the processing conditions to achieve high transmittance on the superhydrophilic surface.
