AI Technical Summary

Technical Problem

Existing vehicle-mounted lenses are difficult to meet the requirements of high-resolution image, miniaturization, telephoto, large field of view, low sensitivity and small main light angle at the same time, and there are also problems such as lens chromatic aberration, astigmatism, and distortion.

Method used

An optical lens consisting of six lenses is designed, including a first lens with a negative optical power, a second lens with a positive optical power, a third lens and a sixth lens, a fourth lens with an opposite optical power and a fifth lens. By reasonably setting the shape and power of each lens, the air spacing and central thickness of the lens are optimized to enhance the control ability and light transmission.

Benefits of technology

It achieves the effects of miniaturization, high illumination, low sensitivity, small main light angle and high resolution, improves the overall performance of the lens, and can meet the requirements of long rear focal and high center angle resolution on the basis of miniaturization.
