摘要：PROBLEM TO BE SOLVED: To regenerate hydrophilic capability of a lens filter anytime, anywhere, easily, and quickly regardless of weather.SOLUTION: By using a lens filter regeneration device, ultraviolet rays are applied with an irradiation strength of 3.0 mW/cmor more so that spots formed on a hydrophilic layer 13 overlap to the hydrophilic layer 13 on a surface of a lens filter 1 from a first UV-LED 31 having a peak wavelength at 375 nm and a second UV-LED 32 having a peak wavelength at 365 nm equipped on a mounting surface of a board 2, and a contact angle of the hydrophilic layer 13 is set to be 20 degrees or less within two hours to regenerate the hydrophilic capability.SELECTED DRAWING: Figure 1
