A shading device for physics experiments

Abstract

The invention discloses a sun-shading device for a physical experiment. The sun-shading device comprises an object carrying experiment table; a light source is arranged at the leftmost end of the upper surface of the object carrying experiment table; a containing box is arranged outside the light source and the pore diameter of an opening is equal to the pore diameter of a light through hole of the light source; a light-color sun-shading plate and a deep-color sun-shading plate are arranged on the right side of the light source in parallel; a sun-shading cover is arranged on the right side of the deep-color sun-shading plate; the light-color sun-shading plate and the deep-color sun-shading plate can be used for weakening strong light and dispersing weak light, so that the effect of separating a light signal is realized; meanwhile, the distinguishing degree of the light signal is improved by one level, so that experiment analyzes of the light signal is convenient to carry out; the centers of a parallel light tube, an optical grid, a lens and an optical fiber are located on the same straight line and the centers of a prism spectrometer and the light through hole are located on the same straight line; and the sun-shading cover is mainly used for integrating and arraying all optical elements, all the optical elements are orderly and uniformly subjected to sun-shading treatment and interferences generated between parasitic light and external light signals are avoided, so that experiment data analysis is simple and convenient and data is accurate and effective.

Description

technical field [0001] The invention relates to the technical field of shading for physical experiments, in particular to a shading device for physical experiments. Background technique [0002] The requirements of physical experiments are different, but when it comes to teaching experiments, the requirements for precision are relatively high. Although the design of the original device is simple, the installation of optical components and the coordination between them are not enough, which will easily cause light deviation, thus in Stray light is generated inside, so the shading device cannot remove the internal stray light, which affects the experimental data. In addition, simply using a shading sheet to shading the light is not only unsatisfactory, but also the stray light is easy to interfere with the equipment and affect the stability of the device. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existin...

[0002] The requirements of physical experiments are different, but when it comes to teaching experiments, the requirements for precision are relatively high. Although the original device design is simple, the installation of optical components and the coordination between them are not enough, which will easily cause light deviation. Stray light is generated inside, so the shading device cannot remove the internal stray light, which affects the experimental data. In addition, the effect of simply using a shading sheet to shading is not ideal, and the stray light is easy to interfere with the equipment and affect the stability of the device.
