"About UV mirror":
UV is the abbreviation of the English word Utlraviolet, UV mirror can filter out the ultraviolet rays in the sun, so it is also called ultraviolet filter.
Because the UV lens can not only improve the image, but also protect the lens from dust, fingerprints and other pollution. and so. The UV lens is always installed in front of the lens without removing it.
Optical glass lens; adopt coating process,High light transmittance! The effect is outstanding!
"Function details":
the firstIt prevents ultraviolet rays. Ultraviolet rays are rays with a wavelength of 200 — 400 nanometers emitted by the sun. It is also the shortest wavelength in sunlight. This kind of rays is invisible to our naked eyes, but it can make photosensitive materials such as film sensitive. This phenomenon reduces the vividness of the color of the captured image. At this time, we can use a UV lens to filter out these ultraviolet rays, reduce the blue-violet light waves transmitted to the photosensitive material, make the distant view clear, and improve the contrast and color saturation of the distant view. In some special occasions, such as plateau, the ultraviolet rays are extremely strong, add a UV mirrorVery much needed.
secondIs to protect the camera lens. Since most of the camera lenses are exposed to the outside, they are easily contaminated by dust, water droplets, oil stains or fingerprints. This requires us to wipe the lens frequently. The camera lens is very delicate and difficult to wear once the mirror surface is worn. Recovery, this will undoubtedly seriously affect the clarity and quality of the picture. In addition, accidental collision and foreign body contact during normal use will cause irreparable consequences. Therefore, a transparent UV protection lens is installed on the outside of the lens to protect the lens from direct pollution or damage. In other special occasions, such as waterside, humid space, unexpected accident scene, especially in harsh shooting environment or windy sand weather, due to many uncertain factors, the lens may be stained. At this time Equipped with a UV lens can protect the lens very well. There is a saying that is not good: ”With UV in hand, you are not afraid of everything”.![](https://img.alicdn.com/imgextra/i1/183666447/TB2QDkfrVXXXXXNXpXXXXXXXXXX_!!183666447.jpg)
