Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing:

[0024] An ultra-high-definition, internal focus virtual reality optical system, including a diaphragm 100, and a first lens 1, a second lens 2, a third lens 3, a fourth lens 4, and a display are sequentially arranged backward from the diaphragm 100 Screen 200, the first lens 1 is a biconvex aspheric lens, the second lens 2 is a meniscus aspheric lens, the third lens 3 is a biconvex aspheric lens, the The fourth lens 4 is a meniscus aspherical lens, and the first lens 1 and the second lens 2 are bonded together with optical glue to form a cemented lens group 300 , and the cemented surface is bent toward the diaphragm 100 .

[0025] The aperture 100 is set at the position 14 mm in front of the first lens 1, which simulates the pupil size of the human eye. The light emitted by the display screen 200 passes through the fourth lens 4, the third lens 3, the second lens 2, the fir...

Abstract

The invention discloses an ultra-high-definition internal focusing virtual reality optical system. The system comprises an aperture (100), and a first lens (1), a second lens (2), a third lens (3), a fourth lens (4) and a display screen (200) are sequentially arranged behind the aperture (100); the first lens (1) adopts a bi-convex aspherical lens, the second lens (2) adopts a crescent-shaped aspherical lens, the third lens (3) adopts a bi-convex aspherical lens, and the fourth lens (4) adopts a crescent-shaped aspherical lens; the first lens (1) and the second lens (2) are bound together through optical glue to form a glued lens set (300), and the glued surface bends towards the aperture (100). The ultra-high-definition internal focusing virtual reality optical system is simple in structure, high in definition, large in view field angle and wide in application range.

Description

【Technical field】 [0001] The invention relates to an optical system, more specifically to an ultra-high-definition, internal focusing virtual reality optical system. 【Background technique】 [0002] At present, virtual reality (Virtual Reality) is on the rise. The principle of VR glasses (virtual reality glasses) is similar to a magnifying glass, which is to enlarge the picture, and the human eye perceives the enlarged picture. The current mainstream product is one-piece, which can realize 3D effect, but the definition is poor, and the feeling of vertigo is strong when watching 3D images. Limited to too few parameters that can be optimized, it is difficult to improve the imaging quality of the lens. For example, aberrations such as dispersion distortion are almost impossible to eliminate with a single lens. Therefore, the lens group solution is the future VR helmet (the lens is mounted on the helmet The development trend of lenses in VR glasses). [0003] Therefore, the pre...
