The function of uv Mirror

1.UV mirror, also known as ultraviolet filter, refers to the filter used in digital cameras. UV mirrors are usually colorless and transparent, and some appear purple or purplish red at a specific angle because of the antireflective film.

The main function of 2.UV mirror is to absorb ultraviolet light with a wavelength below 400 nm and has no filtering effect on other visible / invisible light. Ultraviolet rays can be filtered because the lenses contain lead, so ultraviolet lenses are heavier than other lenses of the same size and thickness. At the same time, the UV mirror can prevent the coating on the surface of the lens from coming into direct contact with the external environment, which plays a protective role.

3.UV mirror is suitable for shooting in seaside, mountain, snow and open areas, which can reduce the blue tone caused by ultraviolet light. At the same time, for digital cameras, it can also eliminate the interference of ultraviolet rays on CCD, which helps to improve the clarity and color restoration effect.
