Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] See figure 1 , the design method of the non-equal thickness optical lens of a preferred embodiment of the present invention comprises the following steps:

[0033] S1: Establish a lens model in optical software, determine the size of the lens model, and determine the pre-thickness of the lens model according to the curvature of the incident surface and the exit surface of the lens model;

[0034] S2: simulating a beam of incident light, the light is incident through the incident surface of the lens model, exits through the exit surface of the lens model, and compares whether the incident light is parallel to the outgoing light;

[0035] S3: If the incident light i...

Abstract

The invention relates to a method for designing non-equal-thickness optical lenses, comprising the following steps: (1) establishing a lens model in optical software; (2) simulating a beam of incident light to illuminate the lens model, and comparing whether the incident light is parallel to the outgoing light (3) if parallel, then record the curvature and thickness of the incident surface and the exit surface of the lens, and make the initial product of the lens; if not parallel, adjust the thickness between the incident surface and the exit surface of the lens model to make it parallel , then record the curvature and thickness of the incident surface and the outgoing surface at this time, and make the primary lens product; (4) verify whether the primary product is qualified, and return to step (2) to start again if unqualified. The lens prepared by the method of the invention can reduce or eliminate the distortion, so that the image is clear, and people will not feel dizzy after using it for a long time.

Description

technical field [0001] The invention relates to a design method of non-equal-thickness optical lenses. Background technique [0002] Lens, also known as mirror heart, is a framed painting heart, which is suitable for being placed in the frame, so it is called mirror heart. Its form can be horizontal or vertical, and it is a simple and convenient installation. With the development of modern technology, the application of lenses has penetrated into all walks of life and our daily life. However, due to its design principle, many lenses are made into lenses with uniform thickness, and their visual effects cannot meet the requirements of most people, such as unclear imaging effects and inability to eliminate distortion. Contents of the invention [0003] The object of the present invention is to provide a design method of non-equal-thickness optical lenses, which can achieve clear imaging and eliminate distortion by adjusting the thickness between the incident surface and the...
