Embodiment

[0029] Such as Figure 1-4 As shown, the embodiment of the present invention provides an achromatic holographic optical device, including a single-sided convex lens 2, a double-sided convex lens 3, and a double-sided concave lens 5. The end faces of the single-sided convex lens 2 and the double-sided convex lens 3 are provided with stepped annular arc surfaces, and each The arc radius of the cross-sectional profile of the arc-shaped surface is consistent. This setting can reduce the axial size of the component, so that the component can be manufactured with less material, reduce the quality, and reduce the material cost. Both ends of the double-sided concave lens 5 are provided with stepped rings arc surface, and the arc radius of each arc surface section profile is consistent, which is consistent with the above-mentioned effect. The single-sided convex lens 2, the double-sided concave lens 5 and the double-sided convex lens 3 are stacked in sequence, so that the stacked parts ...

Abstract

The invention provides an achromatic holographic optical device and a manufacturing method thereof, and relates to the field of optical devices. The achromatic holographic optical device comprises a single-face convex lens, a double-face convex lens and a double-face concave lens. Stepped annular cambered surfaces are arranged on the end faces of the single-face convex lens and the double-face convex lens, and the radiuses of section contour arcs of the cambered surfaces are consistent. Stepped annular cambered surfaces are arranged on the two end faces of the double-face concave lens, and the radiuses of the section contour arcs of the cambered surfaces are consistent. The single-face convex lens, the double-face concave lens and the double-face convex lens are stacked in sequence. The manufacturing method of the achromatic holographic optical device comprises the steps of forming, grinding, stacking and assembling. According to the invention, the size of the optical device can be reduced, and resin gluing is adopted, so that the integrality is good, and dust is not easy to enter.

Description

technical field [0001] The invention relates to the technical field of optical devices, in particular to an achromatic holographic optical device and a manufacturing method thereof. Background technique [0002] When imaging with white light, in addition to the five monochromatic aberrations produced by each monochromatic light, there will also be dispersion caused by different refractive indices of different colored lights, so that different colored lights have different propagation paths, thus showing Aberrations caused by differences in the optical paths of different colors of light. [0003] When traditionally solving the problem of chromatic aberration, such as Figure 5 An achromatic lens with the structure shown: a first convex lens (6), a concave lens (7) and a second convex lens (8). However, the adoption of this structure makes the size of the lens larger, which is not conducive to portability. Contents of the invention [0004] (1) Solved technical problems ...
