What is UA mirror from Shenzhen Home Network? Please, all the gods

UV mirror is an ultraviolet filter (Ultra Violet). The main function of the UV mirror is to absorb ultraviolet light with a wavelength below 400 nanometers. It has no filtering effect on other visible/invisible light. The filtering principle is leaded glass, so it is relatively heavy. UV mirrors are usually colorless and transparent, but due to the influence of the anti-reflection coating, they may appear different colors when viewed at certain angles. In foggy weather and high-altitude environments, ultraviolet rays are relatively strong, and the captured images will be cast in a blue-purple hue. Therefore, adding a UV mirror can absorb ultraviolet rays and eliminate the interference of ultraviolet rays on the CCD, which helps to improve the clarity of the impact. and color restoration effects.
