Aspheric Plastic Lens Case
High-precision aspheric plastic lens can be assembled into AR&VR related products, which can meet the strict requirements of resolution and effectively display clear information. The transmission ratio and stress optical path difference of aspheric plastic lenses can also be adjusted according to specific application requirements, which are widely used in industry, automobile, consumer electronics, medical, cultural tourism, education and other fields.
A Aspheric plastic lens requires high machining accuracy. In the processing, the product needs to be tested and modified repeatedly to avoid possible processing marks and surface defects, and gradually improve the accuracy.
A Aspheric lens, a lens with a curved surface of an aspheric surface. Generally, can be divided into simple surface (such as paraboloid) and combined surface. The aspheric lens with complex calculation can be used to correct the spherical aberration of lens group. Because the aspheric surface can be properly combined to make the center of the lens positive and the edge negative, it can have multiple correction functions at the same time, and in theory, spherical aberration can be reduced to 0.
