Description
Technical field
The utility model is related to virtual display eyepiece technical field, more particularly to a kind of two lenses virtual display eyepiece light
System.
Background technology
Virtual reality technology has started one upsurge in current Wearable market, used as personal consumption in recent years
One of focus, with great market development space.Because the screen size of the electronic products such as mobile phone, panel computer is smaller, sternly
Viewing experience is limited again, is amplified display screen at double before human eye by optical amplifier principle using virtual reality device
Afterwards, viewing experience can greatly be optimized.
Virtual reality device is generally worn on head, and the weight and volume of equipment should not be too big, and is located at before eyes
Eyepiece optical system is the core component of virtual reality device, thus eyepiece optical system design to virtual reality device to closing
It is important.Mainly using traditional single piece type lens arrangement, there is many lacking in this single piece type lens arrangement to current virtual reality device
Fall into, such as aberration cannot be eliminated, visual field edge image blur, distort it is larger etc., although some defects can be by software come more
Mend, such as treatment of anti-distortion etc. in advance, but amount of calculation and precision are all difficult to estimate, and also the bad for the treatment of can cause observation
This dizziness.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of virtual display eyepiece optical system of two lenses, should
Virtual display eyepiece optical system uses bimirror chip architecture, keeps clear etc. excellent with color difference eliminating, the smaller and full filed that distorts
Point.
The technical solution adopted in the utility model is to design a kind of virtual display eyepiece optical system of two lenses, including：
Two monocular optical systems of identical or so, the monocular optical system includes：Be arranged in order from front to back first piece lens,
Second lens and display screen, first piece lens, second lens and display screen are centrally located at same straight line, and human eye is located at the
The front side of a piece of lens.
Wherein, first piece lens are disposed adjacent with second lens, and both center spacing are not more than 0.5mm.
Preferably, first piece lens to the center spacing of display screen in the range of 55mm to 65mm.
Preferably, first piece lens and second lens are respectively adopted different optics plastic materials, and first piece lens can
Using the plastic material of crown board type, second lens can be using the plastic material of flint type.
In the first embodiment, first piece lens are positive lens, and the face type of first piece lens is including at least a piece of aspherical
Face type, second lens are negative lens.First piece power of lens is that 0.037, Abbe number is 57.33, second lens
Focal power is that -0.021, Abbe number is 29.93.
Preferably, the leading flank on second lens towards first piece lens is the curved surface that caves inward.
Preferably, the leading flank of second lens is additionally provided with the locating ring that a circle is set along its edge, first piece lens jacket
In locating ring, one entirety of two panels lens forming.
In a second embodiment, first piece lens are Fresnel Lenses, and second lens is towards the front side of first piece lens
Face is the curved surface for caving inward, and the flexibility of the curved surface is larger so that two panels lens distance closer to.
Compared with prior art, the utility model uses bimirror chip architecture, and two panels lens are disposed adjacent, to reduce system
Physical dimension, while two lenses can distort in color difference eliminating, reduction well, makes full filed keep a clearly picture.This reality
With new structure it is simple, be readily produced, possess great application prospect.
