Description
Technical field
The present invention relates to a kind of laser, specifically, is related to a kind of laser beam expanding lens adjusting apparatus and laser expands
Shu Jing method of adjustment.
Background technology
Growing with laser application, small volume, the indicator type laser demand that in light weight, reliability is high are more next
It is bigger.But this laser is in the fabrication process, axiality but it is difficult to ensure that.Because microlaser is by minimum peace
The limitation of diameter is filled, the method along Laser emission direction mounted lens one by one can only be used to be assembled.Common practice be by
The light source part of laser is fixed on a firm platform, and a receiving screen, laser are placed on certain distance in front of laser
Light source part geometric center be calibrated to receiving screen center it is concentric.Beam expanding lens is placed on installation site during manufacture
Near, carry out it is slight move radially, spot center is fallen on receiving screen in defined scope；Because now laser beam is expanded
Beam mirror dissipates, and a larger hot spot can be presented on receiving screen, it is difficult to its center of accurate judgement, thus causes to assemble shell
After body, laser coaxial degree is difficult to ensure that, the optical quality of laser is deteriorated when serious.
The content of the invention
For drawbacks described above, the invention provides a kind of adjustment of easy, efficient beam expanding lens method of adjustment and practicality dress
Put.This method can directly and accurately judge the axiality of laser, improve the fabrication yield of laser, improve manufacture effect
Rate, it is adapted to batch production.
The technical scheme of the adjusting apparatus of the laser beam expanding lens of the present invention is such：It includes the flat of fixed laser
Platform, platform periphery set the support of fixed platform and convex lens, and support enables the optical centre of laser and convex lens to realize together
Axle center.
The chuck structure or V slot structures of fixed laser are set on platform.
Support makes the optical centre of laser and convex lens concentric.
Speculum makes light path keep the optical centre of laser and convex lens concentric after transferring.
A kind of method of adjustment of laser beam expanding lens, it is characterised in that：It comprises the following steps：
A:The convex lens of proper focal length are selected according to the enlargement ratio of the angle of divergence of laser light source and beam expanding lens；
B:Convex lens are installed on support；
C:Laser is placed into the notch or V slot structures of Laser platform；
D：Laser is rotated, spot tracks are depicted on receiving screen；
E：The central point of meeting glossing up track on receiving screen, using this central point as the center of circle, sets hot spot drop point scope side
Boundary；
F：Beam expanding lens is put into the position to be adjusted of laser；
G：The radial position of beam expanding lens is adjusted, until hot spot falls in the described border of E steps.
The technical program laser beam expanding lens adjusting apparatus includes the platform of fixed laser, and platform periphery sets fixed flat
The support of platform and convex lens, support enable the optical centre of laser geometric center and convex lens to realize and keep concentric, this
The relevant position that sample can is directly put into laser light source and convex lens on platform and support is then complete by fine setting can
Into the installation process of laser beam expanding lens.
The chuck structure or V slot structures of fixed laser are set on the technical program platform, and this structure can ensure to swash
The geometric center of light device keeps constant.
The technical program support makes the optical centre of laser and convex lens concentric, can also support make laser with it is convex
The optical centre of lens is vertical, and intersection sets reflective mirror, can so meet wanting for various forms of laser beam expanding lens
Ask.
The laser of the technical program includes the shell body assembled, and the axiality reference for assembling of such laser is with surveying
Amount benchmark is consistent, and coaxial accuracy is higher, and laser is relatively good toward fixed on platform.
The laser beam expanding lens adjusting apparatus of the present invention carries out slight move radially to beam expanding lens, so that it may so that hot spot point
On receiving screen in defined scope, this method makes to be converted into a small light on receiving screen by the hot spot that beam expanding lens has dissipated
Point, the degree of accuracy of visual determination is greatly improved, simultaneously as shell body is prior to beam expanding lens fit on, it is possible to
The self-test of the assembly work is realized, the fabrication yield of laser is generally improved, manufacture efficiency, is adapted to batch production.
