Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, wear-type optical system comprises eyepiece stalk 1, eyepiece stalk base 2 and display 3, and the bottom of eyepiece stalk 1 is inserted in one end of eyepiece stalk base 2, and the other end of eyepiece stalk base 2 is used for fixing display 3.As Figure 2-3, eyepiece stalk 1 comprises inner bag 11, first group of optical lens 12, second group of optical lens 13, spacer ring 14 and vision accommodation dialing ring 15, first group of optical lens 12 and second group of optical lens 13 are installed in inner bag 11, spacer ring 14 is for encapsulating the bottom of eyepiece stalk 1, vision accommodation dialing ring 15 is arranged on for regulating eyepiece stalk 1 to move up and down in eyepiece stalk base 2 outside eyepiece stalk 1, and the lens edge of first group of optical lens 12 and second group of optical lens 13 is coated with sub-light delustring paint.
In the imaging system of optical instrument, parasitic light is very harmful, wherein greatly from optic periphery.Lens numbers is more, and amount of stray light is larger, thus the imaging definition of lowering apparatus and image quality.May have 3 to 4 optical eyepiece eyeglasses in optical system, lens edge can reflect or diffuse reflection imaging, forms parasitic light, has a strong impact on imaging definition and image quality.The utility model sprays sub-light delustring paint at lens edge, and dried sub-light delustring lacquer coat can meet the delustring requirement of most of optical mirror slip, and Absorbable rod is nearly all from the parasitic light in optical element; Its this product due to its solvent rate of volatilization slower, make sub-light delustring paint have the longer time to infiltrate in the pore of lens edge simultaneously, improve adhesion further and reduce the residual rate of white point; Reduce the defect because lens edge edge damage or damage bring.
Preferably, the inwall of inner bag 11 is also coated with sub-light delustring paint.
Preferably, the inwall of eyepiece stalk base 2 is also coated with sub-light delustring paint.
Preferably, the edge of display 3 is also coated with sub-light delustring paint.
Preferably, the inwall of spacer ring 14 is coated with sub-light delustring paint.
In the present embodiment, as shown in Figure 7, the inwall of inner bag 11 is provided with delustring screw thread 111.Delustring screw thread 111 is fine and closely woven low and deep micro-screw thread, is mainly groove shape, and delustring screw thread 111 is more fine and closely woven better.As shown in Figure 6, when not having delustring screw thread in inner bag, imaging is mixed and disorderly.As shown in Figure 7, after adding one deck delustring screw thread 111 in inner bag 11, parasitic light is consumed absorption, and image quality is high.
Preferably, the inwall of spacer ring 14 is also provided with delustring screw thread.
In the present embodiment, as shown in Figure 1, eyepiece stalk 1 and vision accommodation dialing ring 15 are integrated.Rotate vision accommodation dialing ring 15, eyepiece stalk 1 can be driven to move up and down in eyepiece stalk base 2, to adapt to the demand (myopia and farsighted person) of different user group.Adopt integration can greatly reduce design, production cost, reduce production and processing difficulty, can quantize location etc.
Preferably, the eyeglass of first group of optical lens 12 and second group of optical lens 13 is coated with high antireflection film.Eyeglass can use glass material also can make PMMA resin material; As required can sweetly disposition.High antireflection film is be greater than in lens surface last layer refractive index the film that air is less than eyeglass material, when the thickness of film be incident light in the film wavelength 1/4 time, reflected light on two faces of film, path length difference equals half wavelength just, thus cancels each other.This greatly reduces the reflection loss of light, enhance the intensity of transmitted light.The effect of plating high antireflection film, is equivalent to reflection occurs hardly and through film, thus greatly reduces reflection loss, enhances the intensity of transmitted light.
The utility model has the following advantages:
1, spray sub-light delustring paint, eliminate parasitic light, for user brings the picture of high-resolution, high picture element, low distortion;
2, increase delustring screw thread, be difficult to eliminate by changing parasitic light in the past, image quality distortion is serious, there is the picture element problem being difficult to suppress and eliminate of mirage, ghost image;
3, adopt integration can greatly reduce design, production cost, reduce production and processing difficulty, can quantize location etc.;
4, plate the transmission that high antireflection film can increase light, reduce and reduce the reflection of light, thus improve the transmitance of light, improve image-watching brightness.Watch demand due to user can be met with lower display brightness, also serve the effect in the life-span increasing display.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, other modification some can also be made, also should be considered as protection domain of the present utility model.
