Abstract
The utility model discloses a UV lens. An end of the UV lens is provided with external threads which are matched with threads on an inner side of a camera, and the other end is provided with internal threads which are matched with threads on an outer side of a lens cover. The internal threads and the external threads are two-ring threads. An end of the is provided with the internal threads which are matched with the threads on the outer side of the lens cover, and the internal threads are concretely two-ring threads, so that the lens cover is firmly fixed with the UV lens. Tightness is much better than tightness of an engaging type, and the UV lens has effects of shockproof, dustproof, and scratch resistance. In addition, the other end of the UV lens is provided with the external threads which are matched with the threads on the inner side of the camera, and the external threads are concretely two-ring threads, so that the UV lens is firmly fixed on the camera. Other lens inside are preferably protected, and the UV lens prevents dust from entering the camera.
Description
Technical field
The utility model relates to a kind of apparatus for making a video recording field, relates more specifically to a kind of UV mirror.
Background technology
The UV mirror is called again ultraviolet ray filter, i.e. Ultra Violet.In photography, UV mirror one is len, and magazine camera lens is the most valuable; more protection is necessary; load onto the UV eyeglass, can not allow some dusts corrode, also very convenient in wiping; do not worry to spoil camera lens; the 2nd, be used for filtering light, the UV mirror can weaken because of UV-induced blue cast, simultaneously for digital camera; can also get rid of ultraviolet ray to the interference of CCD, help to promote clearness and the effect of color.
But many people just cannot cover lens cap again after the UV mirror is installed, perhaps namely enable to cover, lens cap is fixed to engage mode with camera or UV mirror, and draw-in groove easily has the slit, cause lens cap fixing insecure, easily produce vibrations, and the dust protection effect is not good enough.And the screw thread of UV mirror and camera bearing is shorter, easily has dust to enter camera lens, affects imaging.
Summary of the invention
The purpose of this utility model is, provide an a kind of end can be directly and the lens cap rotation fixing, the other end and camera seal closely UV mirror.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of UV mirror is characterized in that an end is provided with the internal thread suitable with the lens cap outside screw, and the other end is provided with the external thread suitable with the camera inside thread.
As preferably, described internal thread and external thread are two circle screw threads.
One end of the utility model UV mirror is provided with the internal thread suitable with the lens cap outside screw; and internal thread specifically has two circle screw threads; make lens cap and UV mirror firmly fixing, sealing is good more than clamp-close type, has the effect of shockproof, dust protection, anti-scratch; and; the other end of UV mirror is provided with the external thread suitable with the camera inside thread, and external thread specifically have two the circle screw threads, make the UV mirror tightly be fixed on the camera; better protected other camera lenses of the inside, prevented that dust from entering the inside.
