An L39 UV filter with a 55mm filter thread

UV filters are individual compounds or mixtures to prevent ultraviolet (UV) light from getting through. UV filters are used in sunscreens to protect skin or in photography to reduce the level of ultraviolet light that strikes the recording medium.

Historically, photographic films were mostly sensitive to UV light, which caused haziness or fogginess, and in color films a bluish hue. Therefore, as a standard, a UV (blocking) filter was used, transparent to visible light while filtering out shorter ultraviolet wavelengths. However, newer photographic film and digital cameras are highly insensitive to UV wavelengths. UV filters are sometimes referred to as L37 or L39 filters, depending on the wavelengths of light that they filter out; an L37 filter removes ultraviolet light with a wavelength shorter than 370 nm, whereas an L39 filter eliminates light with a wavelength shorter than 390 nm.

Many photographers and cinematographers still use UV filters as a protection for their lenses' glass and coating, due to their low cost and lack of effect on the exposure of the shot. However, UV filters (in particular filters lacking optical coating) may introduce lens flare and have an adverse impact on contrast and sharpness, especially when a strong light source is present.[1]

However, in photography, the term "UV filter" can be also mean a filter that passes UV light while blocking other wavelengths in the light spectrum, in the same way the term "IR filter" is used. This is a very specialized area in photography.
