Second lens and the glued formation glyglass lens of the 3rd lens 3,
4th lens are used for spherical aberration corrector and aberration,
5th lens are used to control chief ray angle and balance aberration, and the 4th lens and the 5th lens are
Plastic lens.
Further, first lens are in three prismatic, and two transmission planes are aspherical, and the 4th lens are bent moon
Type lens, towards the image planes, the 5th lens are meniscus lens for its concave surface, its concave surface is towards the image planes.
Further, second lens and the 3rd lens face type are sphere, the 4th lens and the described 5th
Lens face type is aspherical.
Further, first lens have positive light coke, and second lens have negative power, and the described 3rd is saturating
Mirror has a positive light coke, and the balsaming lens of second lens and the 3rd lens composition has a positive focal power, and described the
Four lens have negative power, and the 5th lens have positive light coke.
Further, in the turnover light path of first lens, its plane of refraction is aspherical, and reflecting surface is plane.
Further, in the balsaming lens being made of second lens and the 3rd lens, second lens
For high index of refraction, high abbe number material, the 3rd lens are low-refraction, low abbe number material.
Further, the refractive index Nd of second lens meets that 1.85 ＜ Nd ＜ 1.95, its abbe number Vd meet
18 ＜ Vd ＜ 25.
Further, the refractive index Nd of the 3rd lens meets that 1.7 ＜ Nd ＜ 1.8, its abbe number Vd meet 45
＜ Vd ＜ 55.
According to the present invention of such scheme, its advantage is, visual angle of the present invention is big, can reach 40 degree；It has
Away from being 9mm with emergent pupil aperture, camera lens emergent pupil to camera lens most front lens surface distance, the emergent pupil size of camera lens is larger emergent pupil
4.5mm, more sufficient for feeling of immersion after VR equipment, the physiology of people and psychology are more comfortable during viewing；The present invention passes through glass, plastic cement
The collocation of material uses so that is meeting that processing technology is easy, few using lens numbers, the aberration of system is good.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the MTF figures of the present invention.
In figure, the 1, first lens；2nd, the second lens；3rd, the 3rd lens；4th, the 4th lens；5th, the 5th lens；6th, protect
Glass；7th, diaphragm；8th, image planes.
Embodiment
Below in conjunction with the accompanying drawings and the present invention is further described in embodiment：
As shown in Figure 1, a kind of optical system for virtual reality device, including object plane and image planes 8, object plane and image planes 8
Be respectively positioned on before camera lens, between object plane and image planes 8 successively be equipped with diaphragm 7, the first lens 1, the second lens 2, the 3rd lens 3,
4th lens 4, the 5th lens 5 and protective glass 6.
First lens 1 are the plastic cement prism of turnover light path, its similar and prism, two transmission planes are aspherical, are had
The effect of converging beam, so that whole system is done small, for its plane of refraction to be aspherical, reflecting surface is plane.
Second lens 2 and the glued formation glyglass lens of the 3rd lens 3, are mainly used for correcting chromatic aberration so that whole system
The solution picture of system is substantially improved.Wherein the second lens 2 and 3 face type of the 3rd lens are sphere, in addition, the second lens 2 for high index of refraction,
High abbe number material, the 3rd lens 3 are low-refraction, low abbe number material, it is preferred that the second lens 2 meet 1.85 ＜
1.95,18 ＜ Vd ＜ 25 of Nd ＜；3rd lens 3 meet 1.7 ＜ Nd ＜, 1.8,45 ＜ Vd ＜ 55.Here Nd refers to the refraction of lens
Rate, Vd refer to the abbe number of lens.
4th lens 4 are used for spherical aberration corrector and aberration, it is meniscus lens, its concave surface is towards the image planes；5th is saturating
Mirror 5 is used to control chief ray angle and balance aberration, it is meniscus lens, its concave surface is towards the image planes.4th lens, 4 He
5th lens 5 are plastic lens, and its mirror type is aspherical so that whole system has the less curvature of field and distortion, same to time
Beam shooting angle can also match photo-sensitive cell.
First lens 1 have positive light coke, and the second lens 2 have negative power, and the 3rd lens 3 have positive light coke, the
The balsaming lens of two lens 2 and the 3rd lens 3 composition has positive focal power, and the 4th lens 4 have negative power, the 5th lens
