An optical system for virtual reality equipment

Abstract

The invention discloses an optical system used for a virtual reality device, comprising an object surface and an image surface; the object surface and the image surface are positioned in front of a lens; a diaphragm, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a protective glass are arranged between the object surface and the image surface; the first lens is a plastic prism for turning an optical path; the second lens and the third lens form a gummed glass lens through gluing; the fourth lens is used for correcting the ball difference and the color difference; the fifth lens is used for controlling the main light ray angle and a balance image difference; and the fourth lens and the fifth lens are plastic lens. The invention has a wide visual angle achieving a 40 degrees and has a relatively big output pupillary distance and an exit pupil, the surface distance between the lens exit pupil and the lens most front lens is 9; the size of the lens exit pupil is 4.5mm; and after the usage of the VR device, the feeling of involvement is more satisfying, which makes people comfortable when watching the movie.

Description

technical field [0001] The invention relates to an optical system, in particular to an optical system for virtual reality equipment. Background technique [0002] The virtual reality (Viaual Reality, referred to as VR) industry has entered a fast track of development, and domestic consumer hardware products have been mass-produced and launched, but the quality of the products is uneven, resulting in serious dizziness and insufficient immersion in user experience feedback. Affect the healthy and sustainable development of the VR industry. The main reason for these problems is that there is no suitable solution in line with human physiology and psychology, and a suitable optical system is the most important part of it. [0003] The optical lenses used by most manufacturers in the optical part of VR equipment are just a simple single-lens combination, or directly use a single lens to achieve the magnification of the picture. Therefore, the VR equipment on the market has a smal...

Problems solved by technology

[0003] The optical lenses used by most manufacturers in the optical part of VR equipment are just a simple single-lens combination, or directly use a single lens to achieve the magnification of the picture. Therefore, the VR equipment on the market has a small field of view and insufficient immersion; the chromatic aberration is large , seriously affecting the texture of the entire screen, and the user experience is generally poor
