Colorful Ultra Thin Frame UV Filter for Protection of Camera Lens
UV Filters
Basic function:
UV filter can filter out the sun's ultraviolet rays, so it is called ultraviolet ray filter. Usually, it is colorless and transparent, but some of them appear purple or purplish red at some angles because of the antireflection coating. Many people buy UV filter to protect the delicate camera lens, in fact, this is only a subsidiary function for it. UV filter can weaken the blue tone caused by ultraviolet rays. At the same time, for digital cameras, it can also exclude the interference of ultraviolet to CCD, and help improve clarity and color effect.
Key function:
1. Protect lens
2. Filter unwanted ultraviolet light

UV glass Filter Photos:
UV Filter:
Can be used for any type of photography. Polarizing filters are typically circular, allowing for easy control of the effect of polarization.
Optical Filter Advantages:
1)High Transmission,and the optical signal attenuation rate is small, effectively improve the working distance and light intensity;
2)High cut-off rate,effectively prevent stray light interference;
3)High wavelength accuracy
