Abstract
The utility model provides an eyepiece optical system and use its little demonstration optical system, eyepiece optical system includes four lens, observes from the people and surveys the side and arrange in proper order and have first lens, and the focal power is for just, second lens, the third lens of veneer, veneer back focal power is for just, the fourth lens, the focal power is the burden, wherein the second lens with the third lens are plastic aspherical mirror piece, at least one is the glass lens in first lens and the fourth lens. The utility model discloses a cooperation of plastics aspherical mirror piece and glass spheric glass when the eyepiece reduces weight and reduces length, has guaranteed that the exit pupil diameter is big, the field of vision wide, and the formation of image is clear.
Description
Technical field
This utility model relates to optical field, particularly to the optical system of a kind of eyepiece and the microdisplay optical applying it
System.
Background technology
Micro display technology is used on glasses display, and glasses display is increasingly liked by everybody.But it is existing
Micro-display, optical element quantity used in the optical system used by its eyepiece is many so that this eyepiece is longer, micro-display
Weight is relatively big, and user is worn uncomfortable；If reducing the quantity of optical element, causing the visual field narrow, going out diameter little, aberration is big,
Resolution is the highest.Therefore must make improvements.
Utility model content
The purpose of this utility model is to provide a kind of eyepiece optical system, in order to solve eyepiece of the prior art longer,
Weight, compared with big and the eyepiece visual field is narrow, goes out diameter little, and aberration is big, the problem that resolution is the highest.
The purpose of this utility model is to provide a kind of eyepiece optical system, including four lens, from human eye observation side successively
Being arranged with the first lens, focal power is just；Second lens of gluing, the 3rd lens, after gluing, focal power is just；4th lens,
Focal power is negative；Wherein said second lens and described 3rd lens are plastic cement aspherical lens, described first lens and
In four lens, at least one is glass lens.
Compared with prior art, this utility model by the gluing of two plastic aspherical element eyeglasses, plastic aspherical element eyeglass and
The cooperation of glass spherical lens, reduces weight at eyepiece and reduces while length, it is ensured that go out that diameter is big, visual field width, becomes
As clear.
In eyepiece optical system as above, described 4th lens are glass spherical lens.4th lens are glass bead
Face eyeglass can reduce imaging aberrations, improves resolution.
In eyepiece optical system as above, described first lens are plastic cement aspherical lens.
In eyepiece optical system as above, described 4th lens are a meniscus lens.
Another object of the present utility model is to provide a kind of microdisplay optical system using this eyepiece optical system, including
Micro-display control circuit, micro-display on same optical axis and eyepiece, the optical system of its described eyepiece is from human eye observation
Side is arranged in sequence with the first lens, and focal power is just；Second lens of gluing, the 3rd lens, after gluing, focal power is just；4th
Lens, focal power is negative；Wherein said second lens and described 3rd lens are plastic cement aspherical lens, described first lens
At least one is glass lens with in the 4th lens.Compared with prior art, length is short, and volume is little for this microdisplay optical system,
Light weight, imaging clearly；This microdisplay optical system is used in micro-display, people can be made to wear more comfortable, better adaptability.
In microdisplay optical system as above, described 4th lens are glass spherical lens.
In microdisplay optical system as above, described first lens are plastic cement aspherical lens.

For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of this utility model protection.
Fig. 1 is the structural representation of eyepiece described in the utility model, and Fig. 2 is microdisplay optical system described in the utility model
Structural representation, such as Fig. 1, the optical system that the present embodiment provides, including four lens, observe side from human eye 5 and be arranged in order
Have:
First lens 1, plastic cement aspherical lens, focal power is just；
The second glued lens the 2, the 3rd lens 3, are plastic cement aspherical lens, and after gluing, focal power is just；
4th lens 4, glass spherical lens, focal power is negative.
This utility model passes through joining of the gluing of two plastic aspherical element eyeglasses, plastic aspherical element eyeglass and glass spherical lens
Close, reduce weight at eyepiece and reduce while length, it is ensured that go out that diameter is big, visual field width.Also reduce imaging aberrations, carry
High resolution.
4th lens 4 described above are a meniscus lens.
As in figure 2 it is shown, the microdisplay optical system that this utility model provides, including micro-display control circuit, same
Display 7 on optical axis and eyepiece, the optical system of its described eyepiece observes side from human eye 5 and is arranged in sequence with:
First lens 1, plastic cement aspherical lens, focal power is just；
The second glued lens the 2, the 3rd lens 3, are plastic cement aspherical lens, and after gluing, focal power is just；
4th lens 4, convex-concave glass spherical lens, focal power is negative.
Compared with prior art, length is short, and volume is little, light weight, imaging clearly for this microdisplay optical system；This micro display
Optical system is used in micro-display, people can be made to wear more comfortable, better adaptability.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；
Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that:
