The embodiment of present patent application is described below by way of specific instantiation, and those skilled in the art the content disclosed by this instructions can understand other advantages and effect of present patent application easily.Present patent application can also be implemented by embodiments different in addition or be applied, and the every details in this instructions also based on different viewpoints and application, can carry out various modification or change under the spirit not deviating from present patent application.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
As shown in Figure 1, present patent application provides a kind of zoom laser beam expander 1, as shown in the figure, its entirety is preferably cylindrical, the parts of its inside are preferably identical cylindrical, and make can relatively rotate if desired to realize zoom, concrete structure will in hereinafter elaborating.
As shown in Figure 2, be the explosive view of Fig. 1, show the concrete structure of described zoom laser beam expander in Fig. 2, it comprises: housing 11, orienting sleeve 12 and beam expanding lens assembly 13 etc.
See also Fig. 3, described orienting sleeve 12, can be hollow circle tube, has accommodated inside space, has opposite end, preferably, and this both ends open, for convenience of describing, hereinafter referred to as first end 122 and the second end 123, the accommodated inside space penetrated described in described orienting sleeve 12 is formed between described first end 122 and the second end 123, described orienting sleeve 12 wall is at least provided with at least two guiding hollow-out parts 121, as shown in the figure, each described guiding hollow-out parts 121 extends to form (namely from first end 122 to the second end 123 or the second end 123 to first end 122) extend along leading to arbitrary paths of the other end from the one end in described two ends, even with the bearing of trend of this guiding hollow-out parts 121 for vector, then at least can axially important at orienting sleeve 12), concrete, described guiding hollow-out parts 121 can be arc, for example, suppose there is spiral lines outside described orienting sleeve 12, then described guiding hollow-out parts 121 can be offered along the part of described spiral lines, every bar guiding hollow-out parts 121 correspondence has two in conjunction with the hollow-out parts 121 that leads shown in a beam expanding lens assembly 13, figure, but, also can be other quantity in other embodiments, be not limited with the present embodiment, further, the shape of each described guiding hollow-out parts 121 is that each beam expanding lens assembly of spacing as required needs the length of moving to determine in accommodated inside space, and the spacing of each beam expanding lens assembly 13 determines the multiple that laser beam expanding becomes.
As shown in Figure 2, described beam expanding lens assembly 13 has at least two, one_to_one corresponding is in described guiding hollow-out parts 121, as shown in Figure 4, described two beam expanding lens assemblies 13 can be cylindrical, to be located at rotatably in described accommodated inside space and to be arranged in default light path, in the present embodiment, described orienting sleeve 12 is cylindrical shape, described accommodated inside space is cylindrical space, described default light path is axis or its parallel direction of orienting sleeve 12, therefore described at least two beam expanding lens assemblies 13 are arranged along the axial array of described orienting sleeve 12 in described accommodated inside space.
Described beam expanding lens assembly 13 outer wall is fixedly installed and can be incorporated into described guiding hollow-out parts 121 relative sliding and has the convex sliding part 131 be exposed to outside described orienting sleeve 12 of part, in one embodiment, described sliding part 131 is for being fixed on the part of the column of described beam expanding lens assembly 13, for example, column is such as screw, screw rod, bolt etc., certainly, in other embodiments, also can be the column being fixed on beam expanding lens assembly 13 by engaging or bonding mode, or all can with the integrated column of described beam expanding lens assembly 13.
Can derive from figure and obtain: described beam expanding lens assembly 13 rotates in the accommodated inside space in described orienting sleeve 12, described sliding part 131 is driven to slide along described guiding hollow-out parts 121, described beam expanding lens assembly 13 can be made at the two ends (122 of described orienting sleeve 12,123) move between and namely realize described axially-movable, realization like this to the adjustment of each beam expanding lens assembly 13 spacing, thus realizes the adjustment expanding multiple.
On the other hand, preferred but nonessential is, described beam expanding lens assembly 13 also can comprise slide block, it may correspond to disc or the annular of described columniform beam expanding lens element shapes in one embodiment, be embedded in the shell of described beam expanding lens assembly 13, the radial dimension in the accommodated inside space of its radial dimension and described orienting sleeve 12 matches, thus makes that beam expanding lens assembly 13 is smooth and easy in described orienting sleeve 12 stably to slide.
It should be noted that, the example of just a kind of beam expanding lens assembly 13 that Fig. 4 represents, the size of the beam expanding lens comprised according to its inside is different and structure that the is position of its carrying beam expanding lens also has difference, and described at least two beam expanding lens assemblies 13 can adopt the beam expanding lens of different size and corresponding bearing structure according to actual needs.
As shown in figures 2 and 5, described housing 11, may correspond to described is cylindrical shape, and can be sheathed on outside described orienting sleeve 12, in the present embodiment, described relative motion comprises relative motion: such as described orienting sleeve 12 can around its axial rotation in described housing 11, described housing 11 inwall is provided with the stopper slot 111 be combined with the convex part being exposed to described orienting sleeve 12 of each described sliding part 131, in the present embodiment, described stopper slot 111 is such as linear, describe can know by inference in conjunction with said structure, the sliding part 131 of described at least two beam expanding lens assemblies 13 is in conjunction with after described stopper slot 111, when orienting sleeve 12 rotates, the guiding hollow-out parts 121 on described orienting sleeve 12 is made to drive described sliding part 131 to move along it, and, due to the restriction of described stopper slot 111 pairs of sliding parts 131, described beam expanding lens assembly 13 is made to rotate, but can at the two ends (122 of described orienting sleeve 12, 123) (being axial linear movement in the present embodiment) is moved along described stopper slot 111 between.
In addition, preferably, in the present embodiment, the first end 122 of described orienting sleeve is fixed with a beam expanding lens 14, and by its bearing part 15 with described first end 122 secure bond, described engaging can be such as threads, male-female engagement or engaging etc.; The rotation of aforesaid described orienting sleeve 12 is also by operating described bearing part 15 to drive realization.
In one embodiment, the beam expanding lens that described two beam expanding lens assemblies 13 comprise and the beam expanding lens 14 that described first end 122 is fixed, three beam expanding lenss are in same default light path (such as the axis of aforesaid orienting sleeve 12), preferably, eyeglass trim ring by being incorporated into beam expanding lens carrys out pressing and is fixed on respective carrying position, and concrete structure is not described further; By the structure of moving in conjunction with aforementioned beam expanding lens assembly 13, the spacing between adjustable described three beam expanding lenss, thus realize regulating described zoom laser beam expander 1 expand multiple.
