According to comprehensive tests in multiple aspects, the maximum value of the optical reflectivity of the hemispherical concave mirror is 1.2 percent or below, when the average value of the optical reflectivity value is 0.8 percent or below, the color difference does not exist on the whole imaging surface, the hemispherical concave mirror is easy to produce and process, the stability is high, and the optical imaging requirement can be completely met.
Description
Technical field
The present invention relates to eyeglass production technical field, particularly relate to the method that in lens optical vacuum plating, the imaging of hemisphere concave mirror is bad.
Background technology
At present, semisphere concave mirror is widely used in reverse image, monitoring instrument equipment, because its effect is obvious, all actively promotes both at home and abroad.Lens optical plated film is the critical process of hemisphere concave mirror imaging effect quality.Nearly hemisphere concave mirror plated film usually can because of difference of altitude (distance in eyeglass concave surface centerand edge portion) reason, cause the aberration at the edge of concave surface abrasive surface larger, thus there is " ghost " (there is obvious colour-difference the margin and center position of image) in imaging of taking pictures after causing lens assembling, major cause is: 1, the plated film specification of setting and optical band claimed range wide not, the highest setting 420-780nm is not enough to accomplish the plated film scope that concave mirror is comprehensively wider; 2, Film Design aspect, the thickness collocation between each layer is accurate not to concave mirror, so at current optical mirror slip field of vacuum coating, after solving concave mirror assembling, imaging occurs that the phenomenon of " ghost " just seems extremely important.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide and a kind ofly solve the bad method of hemisphere concave mirror imaging, is that film by designing wide wave band and the setting of plated film processing of films system obtain the bad method of a kind of hemisphere concave mirror imaging.
Object of the present invention is realized by following technical solution: a kind ofly solve the bad method of hemisphere concave mirror imaging, comprises the following steps: 1) film design, 2) optical reflectivity specification setting, 3) plated film processing of films system setting, 4) vacuum plating; Be characterised in that:
1), film design: use TFC thin film design software to set the scope of wide wave band: 425nm-1050nm;
2), optical reflectivity specification setting: 425nm-1050nm:Rmax < 1.2%, Rave < 0.8%;
3), plated film processing of films system setting: H4:TiO2 and La2O3 mixture, MGF2 magnesium fluoride;

4), vacuum plating: the optical mirror slip setting film system is placed in vacuum plating unit, eyeglass to be coated faces down and is placed in the collar, again the eyeglass collar is placed on coating equipment running card umbrella, shut vacuum chamber door to vacuumize, 30 minutes pumpdown times of setting, coating temperature 320 ± 20 DEG C, plated film vacuum tightness is at below 2.0*10-5Torr plated film, and plated film terminates namely to obtain optical mirror slip.
The present invention, reasonable in design, simple structure, reliable effect, can conscientiously meet the processing requirement that in eyeglass production process, hemisphere concave surface is glasses lens plated, guarantee quality product.Through many-sided integration test, hemisphere concave mirror optical reflectivity maximum value will below 1.2%, and mean value will below 0.8% time, whole imaging surface does not have aberration and is easy to process for processing, and stability is strong, can reach optical imagery requirement completely again.
Embodiment
For reaching the requirement (i.e. the requirement of " ghost " phenomenon elimination) of optical reflectivity, first selected processing conditions: vacuum plating unit, pumpdown time more than 30 minutes, coating temperature 320 ± 20 DEG C, below plated film vacuum tightness 2.0*10-5Torr.
Secondly, set by plated film processing of films system: CH4:TiO2 and La2O3 mixture, MGF2(magnesium fluoride).

| Process period | 45″ | 40″ | 108″ | 24″ | 336″ | 66″ | 53″ | 372″ |
The scope of optical band is broadened (ultra broadband wave band), requires constantly to improve the setting of film system by Rmax < 1.2%, Rave < 0.8% these 2, finally determine that the scope of optical band is between 425nm ~ 1050nm.Like this, after the setting of film system is relatively fixing, the scope of optical band is fixed by film design (TFC optical thin film design software): 425nm ~ 1050nm.Like this, the imaging of hemisphere concave mirror is bad just can thoroughly solve, and can reach manufacturing requirements completely.
The above-mentioned embodiment enumerated is only illustration of the present invention, is not restriction made for the present invention.The present invention can also adopt alternate manner to implement, and does not state one by one at this.Every employing is equal to the technical scheme of replacement or equivalent transformation formation, all belongs to the scope of protection of present invention.
