Background technology
Laser beam expanding has important application in holographic etc..Laser has good directionality, and monochromaticjty is high, coherence
The advantages that good, had a wide range of applications in laser holography field.Required laser beam will have and compare under normal circumstances
Big beam diameter and the small angle of departure.And the lasing beam diameter that common laser is sent is led between 0.1mm to 1.0mm,
And there is certain angle of divergence, it is impossible to directly meet the needs of actual.The laser that common laser is sent all must basis
Application demand could use after expanding.
The principle that laser beam expanding lens are expanded by it can be divided into refractive and reflection-type.The diametric requirements of outgoing beam are smaller
When, it can typically select refractive.If when being relatively large in diameter of outgoing beam, from reflection-type.Meeting laser beam amplification
Than under conditions of, it should try one's best and select refractive beam expanding lens, because the system architecture of refractive beam expanding lens is simple, be easy to manufacture
And debugging.Refraction type laser beam expanding lens are typically by the concavees lens and the convex lens exported of an input.Mirror is inputted by one
Individual empty focal length light beam sends outgoing mirror to.The laser beam expanding lens of in general low power number are all manufactured with the principle, because its simple, body
Product is small, price is also low.Being limited in that for it is unable to receiving space filtering or carries out expanding for big multiplying power.Although laser beam expanding
The structure of mirror is simple, but existing laser beam expanding lens flexibility lacks, and can not realize the laser beam progress to different wave length
Expand, laser beam exit direction and coaxial line can not be adjusted.If necessary to the exit direction to light beam and position
The use by other governor motions, both inconvenient operator is then needed when being adjusted, also results in the complexity of optical path adjusting.
Need a kind of to expand the laser beam of different wave length, moreover it is possible to realize to laser beam exit direction and position adjustments
Laser beam expanding lens.
The content of the invention

The upper end of dynamic seat is provided with the stage clip for being pressed down against sliding seat, and the sliding seat includes the taper side face tilted down, it is described on
The bottom of microscope base is threaded with four adjusting screws, four adjusting screw circumference array distribution, the adjusting screw
Termination and sliding seat taper circumferential contact, be fixedly connected with eyeglass in the sliding seat.
During using above-mentioned technical proposal, because lower microscope base and cylinder are threaded connection, lower microscope base and cylinder are relatively rotated, will
The distance between lower microscope base and upper microscope base can be adjusted, so as to have adjusted the lower eyeglass in upper eyeglass and lower microscope base in upper microscope base
Distance, so as to serve the effect of laser beam expanding.Furthermore two adjusting screws of relative position are rotated by coordinating, it will
Extruding sliding seat moves horizontally, so as to change position and the refraction angle of lower eyeglass and upper eyeglass light beam, so as to play adjustment
Shooting angle and the effect of position.
Further improvement project, the upper surface of the sliding seat are provided with the groove of installation stage clip., can by setting groove
Stage clip is secured firmly on sliding seat, prevents stage clip from shifting.
Further improvement project, the internal thread through hole run through in the cylinder include two sections, the internal diameter of the epimere
More than the internal diameter of hypomere.The setting can be convenient for installing and rotating regulation.
Further improvement project, the top of the lower microscope base include a vertical lower plug, set on the lower plug
There is the external screw thread with the screw-internal thread fit of internal thread through hole hypomere, and the internal thread of the external screw thread and through hole hypomere is all closely-pitched
Screw thread.It is arranged to fine thread, will can increases the precision of cylinder and the relative rotation of lower microscope base, improve the precision of regulation.
Further improvement project, the bottom of the upper microscope base include a vertical upper plug, upper plug be provided with
The external screw thread of the screw-internal thread fit of internal thread through hole epimere, the middle axial direction of the upper plug are conllinear with the middle axial direction of lower plug.Should
The reference system of the accuracy that processing can be improved and installation is set, the foundation that can also have adjustment when in use.
Further improvement project, the internal diameter of the upper plug are identical with the external diameter of lower plug.The setting, can be in certain journey
Degree optimization structure so that compact overall structure and perfect.
