Abstract
The utility model provides a can realize optical device of laser beam along three direction outgoing, relates to the branch optical element, and it includes a collimating lens, its characterized in that, the place ahead of collimating lens is equipped with a lenticular lens, lenticular lens's both sides respectively are equipped with a light reflecting mechanism, light reflecting mechanism's the reflection of light faces to keeping away from lenticular lens's direction. Behind laser process collimating lens, the reflection takes place through two light reflecting mechanism for partly light, and a part of light takes place the scattering through lenticular lens in addition, just so can guarantee a branch of light of dispersing.
Description
Technical field
The utility model relates to photoelectric field, particularly relates to beam splitter.
Background technology
Laser beam splitter is on the market many just carries out simple light splitting, and the angle of divergence is little, complex structure.
Utility model content
The purpose of this utility model is also that providing a kind of can realize the optical device of laser beam along three direction outgoing, solves above technical matters.
The technical matters that the utility model solves can realize by the following technical solutions:
A kind ofly can realize the optical device of laser beam along three direction outgoing, comprise collimating lens, it is characterized in that, the front of described collimation lens is provided with a lens pillar, the both sides of described lens pillar are respectively provided with a reflection organization, and the reflective surface of described reflection organization is towards the direction away from described lens pillar.
When laser is after collimation lens, a part of light reflects through two reflection organizations, and a part of light is by lens pillar generation scattering in addition, so just can ensure the light of a misconvergence of beams.
The optical axis of described reflective surface and described collimation lens is 45 degree.So just can ensure two bundle reflected light exiting parallel.
In order to obtain the directional light of higher-energy, described reflection organization is a total reflection mechanism.
Two described reflection organizations clamp described lens pillar.On the one hand, the volume of optical device can be reduced, the light of unordered outgoing can be reduced on the other hand.
The bore of described collimation lens is 4.2mm, and face type is aspheric surface.The collimation lens of the preferred PMMA material of described collimation lens.
Described reflection organization is a prism, and the length of side of described prism is 1.4mm.The reflection organization of the preferred k9 glass material of described reflection organization.
Described reflection organization is isosceles prism, one right-angle side of described isosceles prism is glued on described lens pillar, the planes overlapping at the plane at another right-angle side place and a sidewall place of described lens pillar, the bottom of the hypotenuse of described isosceles prism is against on described lens pillar, using the face at the hypotenuse place of described isosceles prism as described reflective surface.
The face at the hypotenuse place of described isosceles prism is coated with reflector layer, forms described reflective surface.
The radius of described lens pillar is 1.8mm.The lens pillar of the preferred k9 glass material of described lens pillar.
The outline of the xsect of described lens pillar is arc-shaped, and the angle of described circular arc is 60 degree to 180 degree, preferably 90 degree.To ensure spread angle, preferred diffusion angle is greater than 90 degree, and then makes application more extensive.
