Abstract
The utility model discloses a kind of integrated beam expanding lens, including a section is circular lens barrel, is respectively provided with a focusing lens at the both ends of lens barrel, and two focusing lens are to be coaxially disposed and the central shaft of lens barrel is through the center of two focusing lens；The utility model is that two focusing lens are arranged in same lens barrel, so ensures that axiality requirement；Two focusing lens can freely arrange in pairs or groups simultaneously, including different specifications all can be selected in the parameter such as diameter, thickness, focal length, and lens barrel is also to be formed by least two sections of different-diameter, and then form the beam expanding lens of different multiplying, meet the selection of different incident beams.
Description
Technical field
Field of optical systems is the utility model is related to, more particularly to integrated beam expanding lens.
Background technology
Beam expanding lens has two big main functions to be widely used in laser equipment optical system due to it：
1, change laser beam spot sizes；2, change the angle of divergence of laser.
Particularly in flight light path, the angle of divergence of laser seems especially important；It directly influences laser and is entering light path
Site effect after being focused on distance light Cheng Duan；Beam expanding lens is mainly fitted together by former and later two focus lamps and formed.
Beam expanding lens is commonly used in the market, and two eyeglasses are separately mounted to two in view of distance is adjustable between two eyeglasses
In individual independent mechanical lens barrel, then one of lens barrel is enclosed in another lens barrel, this design method is due to two lens barrels
Between certain interval be present and easily cause lens barrel not coaxial, and then two eyeglasses are not also coaxial, in flight light path dipped beam end with
Site difference will increase after distance light end focuses on.
Utility model content
The utility model is directed to the deficiency in the presence of above-mentioned prior art, there is provided a kind of to meet the one of axiality requirement
Body beam expanding lens, will two focusing lens be arranged in same lens barrel, so ensure that axiality requirement.
Technical scheme is used by the utility model realizes its goal of the invention：
Integrated beam expanding lens, including a section are circular lens barrel, and a focusing lens are respectively provided with the both ends of lens barrel, and
Two focusing lens are to be coaxially disposed and the central shaft of lens barrel is through the center of two focusing lens.
Preferably, described lens barrel is less first lens barrel of diameter is connected composition with the second lens barrel being relatively large in diameter,
For first, second lens barrel to be coaxially disposed, two focusing lens are separately mounted to the free end of first, second lens barrel.It can so make
Obtaining the focusing lens at both ends can freely arrange in pairs or groups, and reach different multiplying beam expanding lens, meet the selection of different incident beams.
Preferably, the first described lens barrel, the second lens barrel are integrated and are made.
For the ease of installing focusing lens, and ensure the firmness of installation, be used for preferably, being provided with the end of lens barrel
The step surface of focusing lens is installed, focusing lens match somebody with somebody to merge with packing ring, pressure ring to be assembled on described step surface.
Preferably, packing ring is arranged between focusing lens and step surface, focusing lens, packing ring are pressed in phase by pressure ring in the lump
On the step surface answered.
Preferably, the packing ring quantity at lens barrel both ends is different, wherein the packing ring of one end is at least two different-thickness packing rings
Combination.Distance can so be reached between changing focusing lens adjusting the angle of divergence of laser.
Preferably, lens barrel both ends use identical or different-thickness pressure ring.Focusing lens and mirror can so be facilitated
Meet various installation thickness between cylinder.
Preferably, the through hole inside and outside lens barrel is communicated with the side wall of lens barrel.Can be by logical to this when taking eyeglass
Hole is blown, and is taken out by lens barrel inner and outer air pressure difference mirror eyeglass, safely and conveniently.
Preferably, described focusing lens are crescent moon mirror focus lamp.
Employing design starting point of the present utility model, theory and the beneficial effect of above-mentioned technical proposal is：
The utility model is that two focusing lens are arranged in same lens barrel, so ensures that axiality requirement；
Two focusing lens can freely arrange in pairs or groups simultaneously, including the parameter such as diameter, thickness, focal length all can be selected different specifications, and lens barrel
And formed by least two sections of different-diameter, and then the beam expanding lens of different multiplying is formed, meet the selection of different incident beams.
Furthermore the packing ring at both ends can be different-thickness packing ring combination, therefore can reach change focusing lens between
Distance is adjusting the angle of divergence of laser.
Brief description of the drawings
Fig. 1 is the fractionation structural representation of the utility model integration beam expanding lens；
Fig. 2 is the dimensional structure diagram of the displaying its one end state of beam expanding lens in embodiment；
Fig. 3 is the sectional view of beam expanding lens in embodiment.
Embodiment
The technical solution of the utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
Embodiment：Integrated beam expanding lens, as shown in Figure 1, 2, 3, including a section is circular lens barrel 1, the two of lens barrel 1
End is respectively provided with a focusing lens 2, and two focusing lens 2 is are coaxially disposed and the central shaft of lens barrel 1 passes through two focus lamps
The center of piece 2.Described focusing lens 2 are crescent moon mirror focus lamp.
Specifically, described lens barrel 1 is that less first lens barrel 3 of diameter is connected group with the second lens barrel 4 being relatively large in diameter
Into for first, second lens barrel 3,4 to be coaxially disposed, two focusing lens 2 are separately mounted to the freedom of first, second lens barrel 3,4
End.Described the first lens barrel 3, the second lens barrel 4 are integrated and are made.
As shown in figure 3, the step surface 5 for being used for installing focusing lens 2, focusing lens 2 and packing ring are provided with the end of lens barrel 1
6th, pressure ring 7 is assembled in merging on described step surface 5.
Specifically, packing ring 6 is arranged between focusing lens 2 and step surface 5, pressure ring 7 by focusing lens 2, packing ring 6 in the lump
It is pressed on corresponding step surface 5.Further to say, the quantity of packing ring 6 at the both ends of lens barrel 1 is different, as shown in Figure 1,3, lens barrel left end
Packing ring 6 be 1, the packing ring 6 of right-hand member for 8 different-thickness packing rings combination；Certainly, the left and right ends of lens barrel 1 can also use
Number is identical and thickness identical packing ring.
In order to facilitate dismounting eyeglass, the through hole 8 being communicated with the side wall of lens barrel 1 inside and outside lens barrel.
