Embodiment
For above-mentioned and other purposes, feature and advantage of the present invention can be become apparent, cited below particularlyly go out preferred embodiment, and conjunction with figs., elaborate.
Please refer to Fig. 1, measuring fixture 1 provided by the invention can be in order to measure the core shift distance of eyeglass 10, and this measuring fixture 1 includes revolving member 20 and firm banking 30.Firm banking 30 has the support portion 31 and the second hollow axle center 32.20 of revolving members are to include the groove 21 and the first hollow axle center 22.10 on the eyeglass that desire measures core shift is to be placed in the groove 21.At the eyeglass 10 of different size, the size of groove 21 also can change thereupon, and in general, the size of eyeglass 10 can be from 1 φ to 10 φ, and that often use is 8 φ.
In the embodiments of the invention, revolving member 20 essence slightly become right cylinder, and groove 21 is positioned at the upper surface 20a of revolving member 20.When desire measured eyeglass 10, the user can be put into eyeglass 10 groove 21 of revolving member 20 earlier, this revolving member 20 is seated on the firm banking 30 again, and the periphery 20b of revolving member 20 is contacted with the periphery of support portion 31.Contacting of the support portion 31 of revolving member 20 and firm banking 30 can make this revolving member 20 be positioned on the firm banking 30.
When revolving member 20 was positioned on the firm banking 30, revolving member 20 was being supported in the support portion 31 of firm banking 30, and revolving member 20 is located.This moment, the first hollow axle center 22 and the second hollow axle center 32 were linked to be an optical axis L, and therefore the first hollow axle center 22 and groove 21 next-door neighbours can make light cross this groove 21 along optical axis L break-through.Rotate revolving member 20 (direction of arrow rotation as shown in Figure 2) by the user, can make revolving member 20 stably along this optical axis L rotation, to reach the core shift distance of measuring the measurement eyeglass 10 of position on groove 21.Because revolving member 20 will relatively rotate with firm banking 30, so its material is wanted the energy rub resistance, the revolving member 20 of this preferred embodiment and the copper material (for example reaching the hardness of SKD-61) of rough 58 degree of the material hardness essence of firm banking 30.
Another embodiment of measuring fixture 1 ' of the present invention, please refer to Fig. 3, another of this support portion 31 ' implemented aspect and comprised two support columns 313,314, each support column 313 or 314 contacts with revolving member 20 respectively, support revolving member 20 to reach, and revolving member 20 is positioned on the firm banking 30.
Drag in the example in this preferable reality, this support portion 31 or 31 ' can be fixed on the firm banking 30 by fixture, for example utilizes screw 50 as fixture; Must notice that fixture of the present invention is not limited to screw 50, can also utilize similarly be scolding tin connect or even viscose etc. support portion 31 is fixed on solid bottom 30.Perhaps, this support portion 31 also can be integrally formed with firm banking 30.
Please refer to Fig. 4, measuring fixture 1 of the present invention or 1 ' can be applicable on the microscope 4, by the core shift distance of microscope 4 measurement by magnification eyeglasses 10.Typical microscope 4 has guiding device 41 and platform 42, and for instance, this guiding device 41 can be the refracting telescope of position in platform 42.In addition, in this preferred embodiment, this microscopical platform 42 slightly is a certain degree θ with surface level, so revolving member 20 can produce sliding force by the inclination of this certain degree θ, with contact support portion 31 or 31 ', and make revolving member 20 be positioned on the firm banking 30.
As shown in Figure 4, an end of the platform 42 of microscope 4 can be provided with light source I, and light (as the dotted arrow direction of Fig. 4) is crossed the first hollow axle center 21 and the second hollow axle center 32 of measuring fixture 1 or 1 ' from guiding device 41 break-through in the platform 42.In order to measure eyeglass 10, the user can make a mark (not shown), for example criss-cross mark on guiding device 41.Measuring fixture 1 or 1 ' is placed on the platform 42, adjusts revolving member 20 (as Fig. 2 or shown in Figure 3), can make the mark of guiding device 41 aim at this eyeglass 10, reach the core shift distance of measuring eyeglass 10 with this by rotation.
Therefore, the core shift distance by measuring fixture 1 provided by the present invention or 1 ' measurement eyeglass 10 can rotate revolving member 20 regularly, so eyeglass 10 can rotation on microscope 2 firmly.Therefore, can be more accurate so that measure the core shift distance of eyeglass 10, and then action is separated in the throwing that can successfully carry out next technology focusing.
Though the present invention describes as above with preferred embodiment; right its is not in order to limiting the present invention, anyly has the knack of this technology personage, do not breaking away from the spirit and scope of the invention; when can doing a little change and retouching, thus protection scope of the present invention when look application claim defined is as the criterion.
