Abstract
The utility model discloses a combined optical prism. The combined optical prism comprises a first component and a second component, wherein the first component and the second component are glued together. The combined optical prism is characterized in that the first component is a Smit roof prism; and the second component is a half pentaprism. The product can fulfill the aim of rotating an image 180 degrees, and the sizes of optical components and structures in the whole optical system are greatly reduced; after the combined optical prism is applied to telescopes, compared with the traditional telescope, the series of telescopes have the advantages of small size, light weight and convenience for carrying and use; and meanwhile, the telescopes also have an excellent focal length adjustment structure of middle axle focusing and right visual degree compensation of the traditional telescope.
Description
Technical field
The utility model relates to a kind of combining-optics prism, especially relates to a kind of combining-optics prism that can image be done 180 ° of rotations.
Background technology
In bitubular prestige glasses, need use a kind of combining-optics prism as " image construction system ", the effect of this combining-optics prism is can image be done 180 ° rotation.Apply to the bitubular and hope in the glasses that can image to be done 180 ° the traditional optical prism combination inswept rear end of rotation wide, overall volume is big, Heavy Weight; Also volume is big thereby cause the bitubular to hope glasses, and Heavy Weight such as is inconvenient to carry at shortcoming.
Summary of the invention
In order to address the above problem, the utility model provides a kind of can make image 180 ° rotation, and novel structure is unique, little, the lightweight combining-optics prism of volume.
The utility model is that the technical scheme that its technical matters of solution is adopted is:
A kind of combining-optics prism comprises first assembly and second assembly, and first assembly and second assembly are glued together, it is characterized in that: said first assembly is the Si Mite roof prism, and said second assembly is half pentaprism.
Further improvement as such scheme; Said Si Mite roof prism comprises first fully reflecting surface, second reflecting surface, the 3rd fully reflecting surface, first plane of incidence and first exit facet; First fully reflecting surface and first exit facet are same, and the 3rd fully reflecting surface and first plane of incidence are same; Wherein, the angle between first fully reflecting surface and the 3rd fully reflecting surface be 48 ° ± 3 '.
As the further improvement of such scheme, said half pentaprism comprises second plane of incidence, the 4th fully reflecting surface, the 5th fully reflecting surface and second exit facet, and the 4th fully reflecting surface and second exit facet are same; Wherein, the angle between second plane of incidence and the 4th fully reflecting surface is 48 ° ± 3 ', the angle between the 4th fully reflecting surface and the 5th fully reflecting surface is 24 ° ± 3 '.
The beneficial effect of the utility model is: the optical prism of the utility model has adopted by complex-shaped Si Mite roof prism and half pentaprism gummed and has formed; Not only can satisfy the purpose of image being done 180 ° rotation; And greatly reduce the size of optical element and structure in the whole optical system; After this optical prism combination applies to and hopes glasses; The prestige glasses that can make this series and tradition hope glasses compare advantages of small volume, weight slim and graceful, be easy to carry, advantage easy to use, also inherited traditional prestige glasses axis focusing simultaneously, the good focus adjustment structure of right visual degree compensation.
