Formula, this type of projector is than general at 0.18-0.35, and this kind of ultrashort focus projector camera lens generally has two ways, Yi Zhongwei
Camera lens is directly launched, but the design of camera lens and processing are the most highly difficult；Therefore present most ultrashort out-of-focus projection mostly another side
Formula, i.e. uses the reflection mode adding a piece of aspherical lens before camera lens, and the design of this camera lens and processing is the simplest
Single, that sheet non-spherical reflector sheet that camera lens above adds is the highest due to required precision, and its precision can cause projection as localized mode
Stick with paste and deformation, thus be accordingly used in regulation non-spherical reflector sheet most important with the device of camera lens.
Utility model content
The purpose of this utility model is that to solve ultrashort focal length non-spherical reflector sheet due to projection pattern and adding
Projection deformity, projection that work precision causes provide a kind of ultrashort zoom lens non-spherical reflector sheet as the problem of On Local Fuzzy
Adjusting means.
This utility model is attained in that by following proposal and described in the utility model is fixed by non-spherical reflector sheet
On Inclination maneuver seat, Inclination maneuver seat bottom portion one angular position has bulb-shaped recess at, with spherical female on XYZ axial adjustment seat
Falling into relative position has spherical boss at, Inclination maneuver seat fixed screw to be cooperated with spherical boss by bulb-shaped recess,
Two other position, angle of Inclination maneuver seat has inclination angle, left and right set screw and front and back inclination angle set screw respectively, at XYZ axle
Adjusting seat side has anglec of rotation set screw, XYZ axial adjustment seat and six shaft holders to be connected by one group of dovetail groove module, swallow
Regulation X-direction screw, regulation Y direction screw, regulation Z-direction screw are set on stern notch module.
If non-spherical reflector sheet precision when manufacturing molding is not high enough, cause On Local Fuzzy and the change of projection picture
Shape, at this moment inclination angle, the left and right set screw on Inclination maneuver seat, front and back inclination angle set screw adjustable inclination adjust in seat all directions
Angle of inclination, anglec of rotation set screw adjustable inclination on XYZ axial adjustment seat adjusts the anglec of rotation of seat, dovetail groove module
Regulation X-direction screw above, regulation Y direction screw, regulation Z-direction screw regulate XYZ axial adjustment seat in X, Y, Z side
To position, the inclination angle of non-spherical reflector, angles and positions generation minor variations, thus improve the On Local Fuzzy of projection picture
And problem on deformation.
The beneficial effects of the utility model are:
1, a kind of ultrashort zoom lens non-spherical reflector sheet adjusting means of this utility model is by non-spherical reflector sheet
Regulation, it is ensured that projected picture becomes apparent from, and image definition is evenly；
2, a kind of ultrashort zoom lens non-spherical reflector sheet adjusting means of this utility model to non-spherical reflector sheet
Precision prescribed has been relaxed, and then range of application is more extensive；
3, a kind of ultrashort zoom lens non-spherical reflector sheet adjusting means of this utility model controls non-spherical reflector sheet more
Easily operation.
