Abstract
The utility model discloses a novel optic presentation device which belongs to the field of physics teaching aids and comprises a box body, wherein a triple prism, a convex lens and a concave lens are mounted in the box body, light holes are respectively formed on the box body walls corresponding to the triple prism, the convex lens and the concave lens, and windows are formed on the box body wall corresponding to the same side surface of the triple prism, the convex lens and the concave lens. The novel optic presentation device is characterized by simple structure, intuition, high efficiency and the like.
Description
Technical field
The utility model relates to a kind of physical teaching aid, especially a kind of novel optical apparatus for demonstrating.
Background technology
At present, teacher is when demonstrating various lens to interception of rays, demonstrating respectively one by one normally, and then the refraction of summing up between each lens is distinguished, though this way obtains certain effect in teaching, but still can't allow the student distinguish the law of refraction of each lens very intuitively, can not stay deep impression to the student, poor effect.
The utility model content
Technical assignment of the present utility model is to provide a kind of novel optical apparatus for demonstrating at above the deficiencies in the prior art.
The technical solution of the utility model is: a kind of novel optical apparatus for demonstrating, comprise casing, prism, convex lens and concavees lens are housed in described casing, on the box body wall of corresponding prism, convex lens and concavees lens, be respectively equipped with light hole, on the box body wall of corresponding prism, convex lens and concavees lens same side, be provided with form.
During use, simultaneously when three light holes inject in the casing, the student just can observe different lens to interception of rays intuitively by form with horizontal parallel light.
The utility model has the advantages that: simple in structure, can intuitively observe different lens to interception of rays, deepened student's memory.
