Detailed description of the invention

Hereinafter only with embodiment, the form of implementation that this utility model is possible is described, so and be not used to the restriction claimed category of this utility model, close first chat bright.

nullRefer to Fig. 1 to Figure 10，This utility model provides a kind of eyeglass 11 with micro structure、11a、11b、11c、11d、11e、11f (is such as used in the optical glass in lens group 10)，There is one first and one second，At least this first middle body has an optic 111，This optic has a ray machine portion surrounding it，This at least part of region, ray machine portion is formed with at least one recessed micro structure 112、112a、112b、112c、112d、112e、112f，This micro structure 112、112a、112b、112c、112d、112e、The bottom surface of 112f is that cloudy surface is coarse，Such as，This micro structure 112、112a、112b、112c、112d、112e、112f can be formed for laser engraving.

Form about this micro structure more details, in one form of which, this eyeglass 11, 11a, 11b, 11c defines an axis, this axis passes through this eyeglass 11, 11a, 11b, the center of 11c, these micro structures 112 a plurality of, 112a, 112b, 112c is a plurality of annular grooves around the extension of this axis and concentric spacing arrangement, about this annular groove, refer to Fig. 3 and Fig. 3 A, respectively the section of this annular groove is V-arrangement, or as shown in Fig. 4 and Fig. 4 A, respectively the bottom sectional of this annular groove is semicircle, also can such as Fig. 5, Fig. 5 A, Fig. 6, shown in Fig. 6 A, respectively the section of this annular groove is square (square, rectangle or trapezoidal etc.).Preferably, as shown in figure 14, respectively this annular groove has a minimum bottom, between adjacent two annular grooves, there is a highest top, distance d bottom any two adjacent annular grooves is 0.024mm to 0.05mm, the bottom that arbitrary top is adjacent is 8 μm to 12 μm along the distance h of this central axis direction, presss from both sides an angle, θ between two tops that arbitrary bottom is adjacent, and this angle, θ is spent between 60 to 80.This utility model adopts cloudy surface coarse designs especially by annular groove bottom surface, can significantly disperse veiling glare localization effects, coordinate again and press from both sides this angle, θ between two tops of special annular groove distance 0.024mm to 0.05mm and adjacent annular groove between 60 to 80 degree, veiling glare mainly can be allowed to touch the scattered veiling glare refraction in annular groove bottom surface of cloudy surface and the cloudy surface with annular groove two side walls carries out second time veiling glare dispersion effect, to obtain optimization veiling glare elimination purpose.

Fig. 7 then discloses another kind of form, and this micro structure 112d is a plurality of grooves radially extended and be spaced (radial arrangement) around this axis, and the micro structure 112e of Fig. 8 is then one around the spiral helicla flute of this axis.

In addition, as shown in Figures 9 and 10, this micro structure 112f is alternatively a plurality of how pyramidal protrusion and this micro-structure surface is cloudy surface coarse (such as laser engraving formation), it is advantageous to person, respectively this micro structure is corner taper.

By the design of micro structure, can reach to remove the effect of veiling glare.Describe in detail as follows:

Refer to Figure 11 is the light path oblique view before not carrying out micro structure processing, it can be seen that veiling glare is quite concentrated, and significantly affects imaging；Referring again to Figure 12 for carrying out the gorgeous process that disappears of general cloudy surface (when the gorgeous process that disappears refers to produce micro-knot sample annular groove by laser engraving light beam, penetrate engraving light beam via electricity bottom annular groove and irradiate surface formation continuous print fine recesses, annular groove allow because of the fine recesses of bottom micro-knot sample surface formed eliminate veiling glare best results coarse cloudy surface) after light path oblique view, can be seen that compared to before undressed, veiling glare has the situation slightly dispersed, but quite concentrates；Refer to Figure 13 again, for the light path side view of the embodiment of Fig. 3 and Fig. 3 A, it can be seen that processing compared to undressed and simple cloudy surface, veiling glare quite disperses.

From the foregoing, it will be observed that by micro structure of the present utility model, can reach to remove the good result of veiling glare, maintain image quality, improve product yield.
