Geometric-optical comprehensive demonstration instrument

Abstract

The invention relates to a geometric-optical comprehensive demonstration instrument comprising a box body (10) of an optical path display box, a chassis (1) of a laser source and an element group, wherein the upper ends of a front plate and a back plate of the box body (10) are provided with slide rails (7) and an upper cover (8); the chassis (1) is provided with a vertical rod (4), a regulating seat (3) capable of moving along the vertical rod up and down is arranged on the vertical rod (4) and is provided with a laser source fixing seat (5), a laser pen (6) is fixedly arranged on one end of the fixing seat (5), and a laser box (2) is arranged on the other end of the fixing seat (5); and the element group comprises a lens support (11), a convex and concave mirror (12), a plane mirror (13), an angle board (14), a concave mirror (15), a convex mirror (16), a convex lens (17) and a triangular prism (18). According to the technical scheme of the invention, the geometric-optical comprehensive demonstration instrument can carry out demonstration of different kinds according to different teaching contents and has the advantages of clear and bright demonstration light path, strong third dimension comprehensive observation, convenience in operation and the like.

Description

Technical field: [0001] The invention relates to a teaching experiment device, in particular to a geometrical optics comprehensive demonstrator for the physical optics department of a middle school. Background technique: [0002] In the middle school physical optics teaching, it is very important for students to master the laws of optics, understand the light path of optics and make a good light path diagram to do a good job in optical demonstration experiments. Some light sources in existing optical experiments use incandescent lamps to converge into parallel light or decompose them into three beams of red, green and blue light through a prism. It is inconvenient to explain the focus because the convergence and divergence are inconsistent; some use the light source to fix on the display box and only the front side of the box is transparent. During the demonstration, the height of the lens in the box is adjusted, which is extremely inconvenient to operate and cannot be obser...

Problems solved by technology

Some light sources in existing optical experiments use incandescent lamps to converge into parallel light or decompose them into three beams of red, green and blue light through a prism. It is inconvenient to explain the focus because the convergence and divergence are inconsistent; some use the light source to fix on the display box and only the front side of the box is transparent. During the demonstration, the height of the lens in the box is adjusted, which is extremely inconvenient to operate and cannot be observed in all directions. , no three-dimensional effect
