Abstract
The utility model relates to an optical path micro-adjustment device, which comprises at least one optical adjustment plate and an adjustment cap for supporting the optical adjustment plate. The optical adjustment plate is a cuboid or a wedge-shaped body The adjustment cap is semispherical. When the device is used for the micro-adjustment of an optical path, the adjustment cap is placed in a semispherical groove and the optical adjustment plate is placed at an optical path transmission position. Then the adjustment cap is operated to ensure that the optical path micro-adjustment device is swung back and forth and rotated right and left. The angle between light rays and the incident surface of the optical adjustment plate is changed and the optical path is refracted by the optical adjustment plate to be changed in the XY direction based on the large-adjustment and small-variation effect of an optical lever. When the optical path reaches an appropriate position, the adjustment cap and the groove are fixed. Thus, the the problems of low adjustment accuracy of the optical path and difficulty in maintenance of the adjusted optical path are effectively solved. When a laser is coupled to an optical path adjustment process of optical fibers/waveguides, the device has extremely high accuracy requirements on the XY direction. The optical path is extremely and accurately adjusted finely by using the optical path micro-adjustment device.

Condition under, work as n=1.56, L=10, during l=0.7, the angle of optics adjustment plate
rWhen 0 spends in 90 degree scopes monotone increasing and changes, angle
Only spend that monotone increasing changes in the scope of 0.07 degree, promptly in the same distance of adjustment 0
The time, the angle of optics adjustment plate
rThe change amount be far longer than
The change amount at angle.That is to say, in the adjustment of light path, can be through in light path, adding optics adjustment plate, to optics adjustment plate
rThe adjustment of angle wide-angle realizes the change amount to light path
The effect that well " optical lever " adjusted little change is greatly played in fine setting, optics adjustment plate.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists; A kind of light path inching device is provided; Be intended to effectively to solve that error is big in the conventional light path adjustment, precision is low, the problem of adjustment back light path malleable, can better be applied to the adjustment of various miniature light paths.
The purpose of the utility model realizes through following technical scheme:
Light path inching device, characteristics are: comprise at least one optics adjustment plate and the adjustment cap that said optics adjustment plate is supported, adjust the semisphere that is shaped as of cap.
Further, above-mentioned light path inching device, the material of said optics adjustment plate is a light transmissive material.Light transmissive material is a glass.
Further, above-mentioned light path inching device, said optics adjustment plate be shaped as rectangular parallelepiped or wedge body.
Again further, above-mentioned light path inching device, the surface of said optics adjustment plate one side at least is coated with anti-reflection film.
The substantive distinguishing features of the utility model technical scheme is mainly reflected in progressive:
The utility model light path inching device effectively solves low precision in the light path adjustment, the difficult problem that keeps of adjustment back light path; Especially be coupled in the light path adjustment of fibers/waveguides at laser instrument; Its accuracy requirement to XY is high especially; Accuracy requirement all being the following rank of micron, utilizes this light path inching device very accurately light path to be finely tuned.In addition, fixedly there are the characteristics of postwelding displacement in traditional laser bonding, the effect of the utility model utilization " optical lever "; Reduced adjusting the accuracy requirement of miniature light path, need use the place of the higher laser welding process of precision before, just can make processing of glue into; Equally, in the process of fixed light path, because stress; Small change possibly take place in optics adjustment plate self angle; Because " optical lever " of optics adjustment plate adjusted the effect of little change greatly, the change amount of light path will become very little, so also play the effect of well stablizing light path.And semisphere adjustment cap also increased the contact area of this light path inching phase part and fixed groove, makes surface of contact stressed evenly, also reduced because the light path change amount of the effect of material stress generation.Reduce production cost, improved production efficiency, and workable in application, and technology is simple, is adapted at using in the various miniature adjustment light paths.
