3, summary of the invention:
An object of the present invention is to provide the visual optical prism of freely curved face total reflection type, it can shorten light path, and product design is dwindled; Reduce aberrations such as aberration and distortion, can improve the quality of image; Optical element is few, and is in light weight, conveniently wears when being installed in glasses display and adjusts.
Another object of the present invention provides the adjusting mechanism of the visual optical prism emergent light axis depth of parallelism of freely curved face total reflection type, and it can guarantee the visual optical prism by emergent light axis parallelism tolerance numerical value, and is simple in structure.
The visual optical prism of freely curved face total reflection type of the present invention is achieved by the following technical solution:
A kind of visual optical prism of freely curved face total reflection type, it comprises: the plane of incidence, exit facet, reflecting surface, the described plane of incidence is the plane, realizes that light incides in the visual optical prism; Described exit facet is a sphere, will be totally reflected on the reflecting surface from the light that the plane of incidence enters the visual optical prism;
Described reflecting surface is a free form surface, and the light that the reflecting surface exit facet is penetrated is the reflected back exit facet again, is reflected away by exit facet at last and converges to pupil, can see the enlarged image that the visual optical prism forms from pupil.
Above-mentioned described reflecting surface is the free form surface that is made of three space curves.
The face shape feature of relative position between the above-mentioned described plane of incidence, exit facet, the reflecting surface and reflecting surface has specific relation and parameter, and has formed the special optical texture system of the various aberrations of enlarged image and fair copy system.
Above-mentioned described visual optical prism is greater than 1 injection molding by refractive index.
Above-mentioned described visual optical prism also by refractive index greater than 1 glass material manufacturing.
Above-mentioned described free form surface outside surface plating reflectance coating.
Above-mentioned described, it also comprises two mutual parallel planes, and the top on described plane respectively is provided with boss, and the boss end face is provided with rotating shaft.
The adjusting mechanism of the visual optical prism emergent light axis depth of parallelism of freely curved face total reflection type of the present invention is achieved by the following technical solution: it comprises the support that is used to adorn the visual optical prism, adjust two boss on screw, visual optical prism top and the rotating shaft on two boss end faces, the visual optical prism is packed into by the support bottom, adjusting screw is screwed on the support, and push down the visual optical prism, to reach the purpose of adjusting the outgoing parallelism of optical axis.
1), the present invention forms a special visual optical prism by the plane of incidence, exit facet, the surface of emission visual optical prism of freely curved face total reflection type of the present invention compared with prior art has following advantage:, wherein exit facet and reflecting surface are respectively sphere and free form surface, so it can eliminate aberrations such as the aberration of micro display chips display image and distortion, again because exit facet is total reflection, so optical energy loss is little, image quality is clear; 2), shorten light path, product design is dwindled; 3), the present invention is a plastic optics prism, makes the weight saving of product, be convenient to wear; 4), the optical element number is little, planform is simple, is beneficial to assembling; 5), pupil is apart from length, be convenient to observe; 6), magnification is big, be beneficial to observe virtual image; 7), processing technology is single injection-molded, efficient height, waste product is few, cost is low, good in economic efficiency; 8), in product assembling, adjust simply, easily guarantee optical axis outgoing parallelism tolerance numerical value.
1), in product assembling the adjusting mechanism of the visual optical prism emergent light axis depth of parallelism of freely curved face total reflection type of the present invention compared with prior art has following advantage:, adjust simply, easily guarantee optical axis outgoing parallelism tolerance numerical value; 2), simple in structure, fixed convenient and reliable.
