Description
Technical field
The utility model belongs to physics demonstration experiment instrument scope, relates to a kind of interference of light experimental provision, particularly a kind of film interference experimental provision.
Background technology
Film interference is a kind of basic interference of light phenomenon, by on the film, lower surface reflection (or refraction) light beam meets and the interference that produces, film is formed by the very little transparent medium of thickness usually: such as the soap vacuolar membrane, oil film on the water surface, folded air film between two sheet glass, the deielectric-coating that plates on the camera lens etc., fairly simple film interference has two kinds, a kind of equal thickness interference that is called, another kind is equal inclination interference, at present all come the viewing film interference by the film interference demonstrator, but the general area of film that existing film interference demonstrator produces is less, viewing angle is limited, property of participation and interest a little less than.
The utility model content
The utility model purpose: in order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of large-scale, simple and reasonable for structure, film interference experimental provision that can comprehensive viewing film interference.
Technical scheme: in order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of film interference experimental provision, comprise the framework that is consisted of by base, many vertical rods and Duo Gen crossbeam, in described framework and be provided with successively from the bottom up the annular concave liquid bath, with the suitable membrane frame of liquid bath, the jacking gear that rises after the membrane frame is equipped with for lifting membrane frame immersion liquid bath, liquid bath is fixed on the position that is not less than 70cm in the vertical rod apart from substructure height.
Further, described base is annular.
Further, described vertical rod has three also evenly to be vertically connected on the described base, and the quantity of described crossbeam equates with the quantity of described vertical rod.
Further, described membrane frame is annular.
Preferred as jacking gear in the utility model, described jacking gear comprises a plurality of fixed pulleys, an annulus, many stay cords and a handle, described annulus is fixed on the top of described framework, be separately installed with a described fixed pulley at every crossbeam, an end of every stay cord all is fixed on the membrane frame, the other end is walked around the fixed pulley corresponding with its position successively, pass to connect behind the annulus and link to each other with handle.
Stressed evenly and can make the reposefully pull-up from liquid bath of whole membrane frame for each point that makes the membrane frame, described stay cord evenly is arranged on the described membrane frame.
Observe for convenient, in described base, also include the platform of standing for the experimenter.
For the pulling of labour-saving more membrane frame, to be 90 degree spend to 135 the angle of described crossbeam and vertical rod.
Beneficial effect: compared with prior art, the utility model has the advantages that: simple and reasonable for structure, easy to operate, can between membrane frame and liquid bath, form an annular soap film, be conducive to comprehensive viewing film interference, increase property of participation and the interest of experiment.
