Abstract
The invention discloses a device and method for improving the mechanical stability of an imaging optics lens. A classic imaging optics lens structure is further optimized, flexible filler is added in the using process at the same time, the fitting relation among optical elements and mechanical parts of the whole imaging optics lens tends to be more stable, and therefore the mechanical stability of the imaging optics lens is improved.
Description
Technical field
The present invention relates to a kind of device and method improving imaging optical lens mechanical stability, belong to optical engineering
Change application.
Background technology
At present, all kinds of imaging optical lens need according to different imagings, and the optical system that design produces can be in classical knot
Image quality level requirement is met in structure.But classical architecture does not ensure that the Iimaging Stability in practical service environment, power
Learn the important component part that stability is Iimaging Stability.So, inherit using and optimize and develop classical imaging optical lens
Structure, and improve the best mode that mechanical stability is to ensure that Iimaging Stability.
On the other hand, require to step up with to imaging optical lens lightweight, miniaturization and reliability level, need badly
By taking rational method, imaging optical lens internal optical component mutual alignment is kept not change (including rotation, translation), and
Face shape does not change, thus ensureing imaging system stability.
Content of the invention
Present invention solves the technical problem that being: both can ensure that imaging optical lens were good as matter, mechanical environment can be improved again
Lower image quality stability.
A kind of device improving imaging optical lens mechanical stability is it is characterised in that include eyeglass trim rings, filler, light
Learn spacer ring, optical tubes and air-vent, described eyeglass trim rings are external screw thread inner conical structure, and filler is multi-component material,
Optics spacer ring is used for controlling airspace between optical mirror slip, and optical tubes is apparatus main body, corresponding optical mirror slip on optical tubes
Hard-wired locations of structures is designed with filling slot and fill orifice, and air-vent is used for excluding lens barrel inner air.
Described filling slot is discontinuous grooves on lens barrel inwall for the design, and for piling up filler, fill orifice is filling
The aperture of insertion lens barrel in groove, for directly filling filler from outer end.
It is screw thread meshing relation between eyeglass trim rings and optical tubes, play fixation；Optics spacer ring is between optical element
Partition ring, play ensure interelement airspace effect
The present invention compared with prior art has the advantage, that the present invention is not limited by the profile of optics, volume, weight
System, ensure that optical tubes mechanical stability, thus ensureing image quality stability；The present invention is applied to visible light optical
Device, infrared band optics and ultraviolet band optics；The present invention is applicable not only to general optical device, is also suitable
Optics in large-scale optical device is debug.
Brief description
Fig. 1 is optical lens structure chart of the present invention；
Fig. 2 is the partial structural diagram of the optical lens assembling eyeglass of the present invention；
Fig. 3 is the optical lens partial structural diagram being provided with embedding groove of the present invention；
Specific embodiment
If Fig. 1 is optical lens structure chart.Assembly of the invention is by eyeglass trim rings 1, filler 2, optics spacer ring 3, optics
Lens barrel 4 and air-vent 6 etc. form.Eyeglass trim rings 1 are external screw thread inner conical structure, internal conical surface taper optometry minute surface radius
Depending on.After being screwed into optical tubes 4, form tangent plane between optical mirror slip 5 and contact；Filler 2 is multi-component material, along optical frames
On cylinder, the injection of filling hole, natural coagulation, are formed radially flexible contact point in optical mirror slip；Optics spacer ring 3 is used for controlling optical frames
Airspace between piece, when contacting with convex spherical optical mirror plane, using internal conical surface structure, forms tangent plane contact；Optical tubes 4 is
Apparatus main body, corresponding optical lens structure Position Design has filling slot and fill orifice, and filling slot is design on lens barrel inwall
Discontinuous grooves, for piling up filler；Fill orifice is the aperture of insertion lens barrel in filling slot, for from outer end, directly filling is filled out
Fill agent.The two connection；Optical mirror slip 5 is imaged body, according to being actually needed design；Air-vent 6 is used for excluding the internal sky of lens barrel
Gas.
Debug according to common process, precise measuring optical eyeglass loads the airspace after optical tubes, revise optics every
Circle, makes each airspace meet design requirement it is ensured that image quality.Eyeglass trim rings, between optics spacer ring and optical lens convexity
Tangent plane contacts, and can avoid the deformation that stress concentration causes, and also can play automatic centering effect simultaneously.
Debug after meeting image quality, 4 fill orifices reserved by optical tubes circumference, by symmetric relation, by 6
Atmospheric pressure fills the viscosity filler of hybrid modulation in filling slot, and solidification forms 4 flexible fastening strong points.Make optical frames
Piece is fixed in lens barrel interior location, during by external force, changes little and can reply, finally ensures Iimaging Stability.
Finally, fill silicon rubber in the external screw thread engagement place of in front and back's eyeglass trim rings, be allowed to axially can not wriggle.
Fig. 2 is the profile along optical axis direction.
The comprising the concrete steps that of the method for work of the present invention:
Step 1. places optical mirror slip 5, optics spacer ring 3 arrives inside optical tubes 4, accurately measurement 5 air of optical mirror slip
Interval, revises optics spacer ring 3, makes airspace meet design requirement；
Step 2. places optical mirror slip 5 in the correct order, optics spacer ring 3 arrives optical tubes internal 4, is screwed into eyeglass pressure in front and back
Circle, after stablizing, tests image quality；
After step 3. image quality meets design requirement, irrigate viscosity filler, normal temperature places solidification；
Step 4. tests optics lens imaging quality, meets after requiring, fills silicon rubber in eyeglass trim rings 3 site of engagement.
