Abstract

The invention provides a compact 2X high-definition zoom glass-plastic lens, comprising a lens cone. The lens cone comprises an anterior lens A, a posterior lens B and an aperture C that are successively arranged from left to right along incident light. The anterior lens A comprises a first meniscus lens A, a biconcave lens A, and a second meniscus lens A that are successively arranged from left to right along incident light. The posterior lens B comprises a biconvex lens B, a first aspherical lens, a second aspherical lens, a first meniscus lens B and a second meniscus lens B that are successively arranged from left to right along incident light. The compact 2X high-definition zoom glass-plastic lens of the invention is reasonable in design, and achieves a high-definition camera level with an ultra-low cost by using a plastic aspherical surface, realizes 2x zooming and reasonable distribution of focal power, and can still obtain a perfect image in a harsh environment at different temperatures. By ingeniously arranging the position of the aspherical surface, the zoom lens with an ultra-small structure is achieved, so that the lens is practical.

Description

technical field

[0001] The invention relates to a compact 2-times high-definition glass-plastic zoom lens and an imaging method thereof. Background technique

[0002] Currently, there are various 2x zoom lenses on the market for use in security systems. However, due to the glass spherical surface design, it is difficult for the lens to meet the market demand in terms of pixels, performance and cost. At the same time, the complex structure makes it difficult to realize the expectation that the zoom lens can also be small and light. In order to improve performance and pixels, more glass lenses are used to achieve higher-definition image quality, which greatly increases product costs and makes product promotion more difficult. At present, in the security industry, there are few low-cost, high-quality, compact high-definition multi-point zoom lenses in the true sense. Contents of the invention

[0003] The present invention improves the above problems, that is, the technical...
