Description
Technical field
The present invention relates to a kind of laser instrument, specifically, relate to the method for adjustment of a kind of laser instrument beam expanding lens adjusting gear and laser instrument beam expanding lens.
Background technology
Growing along with laser application, the indicator type laser instrument demand that volume is little, lightweight, reliability is high is increasing.But this laser instrument is in manufacture process, and right alignment but is difficult to guarantee.This be because, microlaser is subjected to the restriction of minimum installation diameter, can only adopt along the Laser emission direction one by one the method for mounted lens assemble.Common way is that the Lights section with laser instrument is fixed on the firm platform, places a receiving screen on the certain distance of laser instrument the place ahead, and the geometric center of the Lights section of laser instrument and receiving screen center have been calibrated to concentric.During manufacturing beam expanding lens is placed near the installation site, carries out slight moving radially, in the scope that spot center is fallen stipulate on the receiving screen; Because this moment, laser beam was dispersed by beam expanding lens, can present a larger hot spot on receiving screen, was difficult to accurately judge its center, after causing thus assembling shell body, the laser coaxial degree is difficult to guarantee, also can makes the optical quality variation of laser instrument when serious.
Summary of the invention
For defects, the invention provides a kind of easy, efficient beam expanding lens method of adjustment and practical adjusting gear.The method can be judged the right alignment of laser instrument directly and accurately, has improved the fabrication yield of laser instrument, has improved manufacturing efficient, is fit to batch production.
The technical scheme of the adjusting gear of laser instrument beam expanding lens of the present invention is such: it comprises the platform of fixed laser, and the platform periphery arranges the support of stationary platform and convex lens, and support makes the optical centre of laser instrument and convex lens can realize concentric.
Chuck structure or the V groove structure of fixed laser are set on the platform.
Support makes the optical centre concentric of laser instrument and convex lens.
Catoptron makes the rear optical centre concentric that keeps laser instrument and convex lens of light path turnover.
A kind of method of adjustment of laser instrument beam expanding lens is characterized in that: it comprises the following steps:
A: the convex lens of selecting proper focal length according to the enlargement ratio of the angle of divergence of laser light source and beam expanding lens;
B: convex lens are installed on the support;
C: laser instrument is placed in the notch or V groove structure of laser instrument platform;
D: rotate laser instrument, depict spot tracks at receiving screen;
E: at the central point of receiving screen meeting glossing up track, take this central point as the center of circle, set hot spot drop point range boundary;
F: beam expanding lens is put into the position to be adjusted of laser instrument;
G: adjust the radial position of beam expanding lens, go on foot in the described border until hot spot drops on E.
The technical program laser instrument beam expanding lens adjusting gear comprises the platform of fixed laser, the platform periphery arranges the support of stationary platform and convex lens, support makes the optical centre of laser instrument geometric center and convex lens can realize and keep concentric, so just can directly be put into the relevant position of platform and support to laser light source and convex lens then through finely tuning the installation process that just can finish the laser instrument beam expanding lens.
Chuck structure or the V groove structure of fixed laser are set on the technical program platform, and this structure can guarantee that the geometric center of laser instrument remains unchanged.
The technical program support makes the optical centre concentric of laser instrument and convex lens, also can make laser instrument vertical with the optical centre of convex lens by support, and the place, point of crossing arranges reflective mirror, can satisfy like this requirement of multi-form laser instrument beam expanding lens.
The laser instrument of the technical program comprises the shell body that has assembled, and the right alignment reference for assembling of laser instrument is consistent with measuring basis like this, and coaxial accuracy is higher, and laser instrument is relatively good fixing on the platform.
Laser instrument beam expanding lens adjusting gear of the present invention carries out slight moving radially to beam expanding lens, the hot spot point is in the scope of stipulating on the receiving screen, the method makes the hot spot of having been dispersed by beam expanding lens be converted into a little luminous point at receiving screen, improved greatly the accuracy of visual determination, simultaneously, because shell body is prior to the beam expanding lens fit on, so can realize the self check of this assembly work, improve generally the fabrication yield of laser instrument, made efficient, be fit to batch production.
