Abstract

The invention discloses an eyepiece optical system. The eyepiece optical system comprises a first lens, a second lens, a third lens and a fourth lens in sequence from the eye side to the display side. According to the eyepiece optical system, the overall length of the eyepiece optical system is shortened through the design of the concave-convex configuration of four lens surfaces, and good optical performance, short effective focal length, and large field angle can also be achieved.

Description

technical field [0001] The invention relates to an eyepiece optical system, in particular to a four-piece eyepiece optical system. . Background technique [0002] Due to the advancement of technology, consumers' demand for small electronic products continues to increase. The features applied to the eyepiece optical system, the key components of the eyepiece optical system integrated in consumer electronics products should keep pace with the progress of technology to meet consumer expectations. Some important characteristics of an eyepiece optical system include image quality and size. Under the condition of miniaturized products, the improvement of image sensor technology plays an important role in maintaining (or improving) consumers' expectations for image quality. However, current eyepiece optical systems have some disadvantages, such as too small field of view and / or too large aberrations. Furthermore, it will be a great challenge to reduce the size of the imaging le...
