Problems solved by technology

[0003] The optical system of the current VR display products is usually a single-piece lens. In order to meet the requirement of high definition under a large viewing angle, the distance between the lens and the display screen will be relatively long, which leads to VR display products. The overall size increases, which in turn leads to increased weight and less comfort for the user to wear

Abstract

The invention relates to the technical field of VR equipment, in particular to an optical system and VR equipment. The screen is used for providing imaging light, and the first optical lens group and the second optical lens group are sequentially arranged at an interval in the propagation direction of the imaging light; the first optical lens group comprises a first lens used for reflecting imaging light; the semi-transparent and semi-reflective film is arranged on the side, close to the screen, of the first lens. The second optical lens group comprises a second lens used for turning imaging light; the optical film group is arranged on the side, away from the first lens, of the second lens; according to the optical film group, a first quarter-wave plate is arranged on the side, away from a first lens, of a second lens; and the polarization reflection film is arranged on one side, far away from the second lens, of the first quarter-wave plate. The thicknesses of the first lens and the second lens in the optical system can be greatly reduced, so that the weight of the VR equipment can be greatly reduced. And the optical system in the invention can further improve the imaging quality.

Description

technical field [0001] The present invention relates to the technical field of VR equipment, in particular to an optical system and a VR equipment. Background technique [0002] Virtual Reality (VR for short) is a technology that uses a computer-generated simulated environment to immerse users into the corresponding environment through a corresponding optical display system. [0003] The optical system of the current VR display products is usually a single-piece lens. In order to meet the requirement of high definition under a large field of view, the distance between the lens and the display screen will be farther, which leads to the VR display products. The overall size of the device increases, which in turn leads to an increase in weight and poor user comfort when wearing it. SUMMARY OF THE INVENTION [0004] In view of this, the present invention provides an optical system and a VR device, which at least partially solve the problems existing in the prior art. [0005...
