How to choose a UV mirror?

Ultraviolet microscope can be divided into:

1. ultraviolet

2. Ultraviolet (MC)

3. ultraviolet (HMC)

4. ultraviolet rays

5. Ultraviolet (oxidation)

6. ultraviolet (HMC)

The above are all kinds of signs of UV mirror.

When purchasing a UV mirror, it should be noted that the installation of the UV mirror can not produce a color cast effect on the photos taken in normal environment, and the wide-angle end, especially the telephoto end, can only be clearly focused after the camera is equipped with a filter.

If UV mirror is not plated to enhance transparency, its transmittance is only 90%. Ordinary UV mirrors are double-sided and single-coated, and the light transmittance is about 96%. In addition, there is a multi-layer coated MC UV mirror with a light transmittance of 99.9%, which is much better than ordinary UV mirrors and can completely retain the characteristics of the original lens. ?
