Athermalization high-definition wide-angle lens

Abstract

The invention discloses an athermalization high-definition wide-angle lens, and relates to the field of wide-angle lenses. The athermalization high-definition wide-angle lens sequentially comprises afirst lens, a second lens, a third lens and a fourth lens from an object space to an image space, the first lens is provided with a first convex surface facing the object space and a first concave surface facing the image space, the second lens is provided with a second convex surface A facing the object side and a second convex surface B facing the image side, the two sides of the third lens areprovided with third convex surfaces, the fourth lens is provided with a fourth concave surface A facing the object side and a fourth concave surface B facing the image side, and the second lens is a glass lens. The first lens, the third lens and the fourth lens are plastic aspherical lenses. According to the wide-angle lens, the mounting and dismounting process is simplified through a dismountingmechanism, the anti-vibration and anti-shake effects are achieved, the dual effects are achieved, the use requirement for the lens loaded on the electronic device is met to a great extent, and a goodpopularization effect is achieved.

Description

technical field [0001] The invention relates to the field of wide-angle lenses, in particular to an athermalized high-definition wide-angle lens. Background technique [0002] With the advancement of technology, digital cameras or digital video cameras have gradually replaced traditional mechanical cameras and become the mainstream in recent years. In addition to video cameras and cameras, electronic devices such as monitoring equipment, driving recorders, mobile phones, game consoles, and notebooks are also equipped with lenses to provide video recording functions. The size of existing electronic devices such as driving recorders, mobile phones, game consoles, and notebooks is gradually miniaturized. Correspondingly, the requirements for lenses mounted on these electronic devices are getting higher and higher. Not only must they meet the requirements of miniaturization and low cost limitations, and the need to maintain good image clarity over a wide temperature range. [...

AI Technical Summary

Problems solved by technology

[0003] Wide-angle lenses and electronic products are often fixedly assembled, but with the increasing maturity of technology, it is becoming more and more practical to disassemble wide-angle lenses relative to electronic products. Traditional disassembly mechanisms often only have a single assembly function, which cannot reach other However, during the use of wide-angle lenses, the stability requirements are relatively high. Most of the existing wide-angle lenses have optical anti-shake function. This invention designs a new disassembly mechanism to achieve the effect of auxiliary anti-vibration and anti-shake
