How to improve the efficiency of optical transmission? 1, optical coupling design: The optical coupling between the fiber bundle and the lens is the key to improve the efficiency of the optical transmission. This can be improved from two aspects: first, generally face of optical fiber bundle is flat, if the incident end is changed to the convex, saturation of optical beam can improved, in order to ensures the end face is with full load uniform irradiation, it can add a small flat convex lens on the optical beam end; second, add a light collecting mirror on the emission end face and decreases emergent light angle and become parallel light. It should be emphasized that the number of optical coupling should be reduced as much as possible, preferably one fiber to the end, because each coupling will increase a lot of light loss.

The branch fiber bundle is usually 4~6 heads. The diameter distribution of the branch fiber bundle is as small as possible (this value is limited by the objective lens structure). There are 3 types distribution patterns: uniform, unilateral and bilateral. According to our practice, bilateral is more ideal, the illumination is high and the lining is good.

The fiber bundle with high transmissivity should be selected, and the length of the fiber bundle should be as short as possible, because the output light intensity will decrease with the increase of the length of the fiber bundle. Also, we should pay attention to the diversity of use, such as if light source is mercury lamp, for good transmission of ultraviolet light, the beam must be made by the glass which can be transmitted through the ultraviolet spectrum region.

In accordance with the above methods to improve the efficiency of optical transmission, we should also pay attention to the selection of stable optical fiber media converter.
