Description
Technical field
The utility model relates to optical field, in particular to a kind of raising high definition zoom lens dress school efficiency and image quality
Device, it, which is applicable to silent frame, the fields such as the security protection of high imaging quality, industrial automation video camera lens
Fill school and detection.
Background technique
As video camera develops to high definition, big picture, high sensitivity direction, the requirement to optical lens is increasingly
The assembly of height, optical lens is consequently also increasingly difficult to.In order to solve this problem, processing essence of the camera lens manufacturing enterprise components
Degree is continuously improved.Such as the edging concentricity of eyeglass, outer-diameter accuracy and lens barrel internal diameter cooperation precision are greatly improved, considerably increased
Processing cost.Further, since cooperation is tighter, keep dress school also relatively difficult (dress school is substantially required once to succeed).It can be
On the basis of loosening machining accuracy and raising dress school efficiency mentioned above, guarantees that camera lens silent frame image quality is high, be current
The key that video camera lens develop to high definition, big picture, high sensitivity direction.
According to the tolerance of optical system calculate, influence of each optical component to last image quality be it is different, have
It is required that very tight, some is more loose.In lens thickness and glass material control after a certain range, according to calculating and practical experience table
Bright, the quality of camera lens image quality is not coaxial caused by the optical axis of eyeglass and the mechanical axis of lens barrel.Wherein there are a piece of eyeglass or mirror
The not coaxial property of group influences maximum.In addition, the coaxial deviation of synthesis of other lens assemblies formation can also be made up with it, reach school
The effect of positive camera lens image quality.We claim, this eyeglass or microscope group are that " key component " (it may be that monolithic is also likely to be glued
Piece), the effect of corrective lens image quality can be realized by adjusting " crucial piece " position.
This method initially applies the high x Microscope Objective in more difficult dress school, by adjusting wherein a piece of " key component ",
The asterism image tune circle of observation.In heavy caliber telescopic system, also has using mobile " crucial piece " method and correct image quality.Currently,
Some camera lens manufacturing enterprises carry out high definition multifocal camera lens and industry are automatic using the monochromatic light path method of adjustment " key component " optical axis
Change the dress school of pick-up lens.Since " key component " and the component optical axis of front and back are not coaxial, make the supercentral cross hairs picture of graticle
It is not overlapped with the center (it has been mixed up with optical axis with the concentric coaxial optical system of mechanical axis in advance) of picture pick-up device, passes through tune
Whole " key component " is overlapped them, achievees the purpose that correct image quality.The deficiency of these methods is: can only guarantee intermediate region image quality
School is good, can only guarantee at random the picture quality of full filed, and after camera lens point adhesive curing, cannot detect in due course whether image quality becomes
Dynamic problem.
