Abstract
It is one combined achromatic lens used on video eyewear. It consists of two positive lenses and one double-sided negative lens. The two positive lenses are installed on both sides of the double-sided negative lens respectively. The positive lenses are clamped to the projecting platforms on both sides of the double-sided negative lens via the slots at both lateral ends of the positive lenses. There are air clearances where the double-sided negative lens is connected to the two positive lenses. With a simple structure and simplified manufacturing techniques, it can more effectively guarantee product quality. The three lenses may be nonspherical plastic lenses. They can effectively eliminate image distortion and color difference, get smoother and clearer images, effectively reduce product weight and decrease product costs. The air clearances where adjacent lenses meet together can eliminate color differences, save materials and reduce costs.
Description
1, technical field:
The utility model relates to a kind of apochromatism compound lens that is used for glasses display.
2, background technology:
The principle of glasses display is that optical system will be installed in the eyeball that image that the micro display chips of glasses display the inside shows is amplified into the people.In order to eliminate the aberration that amplifies the back image, in the optical system of micro display chips back, use the apochromatism compound lens.But there is following shortcoming in the apochromatism compound lens that existing glasses display uses: 1) each apochromatic lens all has three sheet glass lens to form complex process with photosensitive glue glued adhesion together; 2) glass lens is heavier, increases the support load of user face, and distortion occurs when watching image, and especially edge is more obvious; 3) optical element long processing time, the rejection rate height increases cost.
3, summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of apochromatism compound lens that is used for glasses display.
The utility model is that a kind of technical scheme is following realization:
A kind of apochromatism compound lens that is used for glasses display, it is made up of two positive lenss and a two-sided negative lens, and two positive lenss are installed in the both sides of two-sided negative lens respectively.
Above-mentioned described positive lens is fastened on the shoulder boss of two-sided negative lens both sides by the draw-in groove at two, side.
The clearance is all left at the junction surface of above-mentioned described two-sided negative lens and two positive lenss.
Above-mentioned described two-sided negative lens and two positive lenss are plastic lenss.
Above-mentioned described two-sided negative lens and two positive lenss can be the aspheric surface plastic lens.
Above-mentioned described two positive lenss are identical.
Another kind of technical scheme of the present utility model is following realization:
A kind of apochromatism compound lens that is used for glasses display, it is made up of two negative lenses and a two-sided positive lens, and two negative lenses are installed in the both sides of two-sided positive lens respectively.
The clearance is all left at the junction surface of above-mentioned described two-sided positive lens and two negative lenses.
Above-mentioned described two-sided positive lens and two negative lenses are plastic lenss.
Above-mentioned described two-sided positive lens and two negative lenses are plastic aspherical element eyeglasses.
Above-mentioned described two negative lenses are identical.
The utility model compared with prior art has following advantage: 1) the utility model can directly be fitted in three lens together, makes the apochromatism compound lens simple in structure, simplified manufacturing technique, quality that can more effective assurance product; 2) three lens can be the aspheric surface plastic lens, and effectively the distortion of removal of images and aberration make picture smooth clear; 3) three lens are plastic lenss, effectively alleviate product weight, reduce cost of products; 4) leave the clearance at the junction surface of adjacent two lens, reach the effect of color difference eliminating, can save material simultaneously, reduce cost.
4, description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a kind of structure principle chart of the present utility model.
5, embodiment:
Embodiment 1: as shown in Figure 1, the utility model is made up of 1,3 and two-sided negative lenses 2 of two positive lenss, and two positive lenss 1,3 are installed in the both sides of two-sided negative lens 2 respectively.Positive lens 1,3 is fastened on the shoulder boss 7 of two-sided negative lens 2 both sides by the draw-in groove 8 at two, side.Clearance 4 is all left at the junction surface of described two-sided negative lens 2 and two positive lenss 1,3.Two-sided negative lens 2 and two positive lenss the 1, the 3rd, plastic lens.Two-sided negative lens 2 and two positive lenss the 1, the 3rd, the aspheric surface plastic lens.Above-mentioned described two positive lenss the 1, the 3rd, size, parameter are identical.
People's eyeball 5 is watched the effectively aberration and the distortion of removal of images of image on the micro display chips 6 by the utility model, makes picture smooth clear.
Embodiment 2: a kind of apochromatism compound lens that is used for glasses display, and it is made up of two negative lenses and a two-sided positive lens, and two negative lenses are installed in the both sides of two-sided positive lens respectively.
Technical scheme principle among technical scheme among the embodiment 2 and the embodiment 1 is basic identical, and only two positive lenss with embodiment 1 change two negative lenses into, changes the two-sided negative lens of embodiment 1 into two-sided positive lens.
The clearance is all left at the junction surface of above-mentioned described two-sided positive lens and two negative lenses.
Above-mentioned described two-sided positive lens and two negative lenses are plastic lenss.
Above-mentioned described two-sided positive lens and two negative lenses are aspheric surface plastic lens.
Above-mentioned described two negative lenses are identical.
