Network Newton's rings experiment instrument based on laser parallel optical pipes

Abstract

The invention discloses a network Newton's rings experiment instrument based on laser parallel optical pipes. The network Newton's rings experiment instrument mainly comprises a public bottom plate, a microscope and a polariscope assembly, wherein a two-dimensional moving platform, a polariscope installing frame, a camera installing frame, a motor installing frame and a plurality of adjustable rod frames are respectively arranged on the public bottom plate; a Newton's rings installing plate is arranged above the two-dimensional moving platform through an adjustable Newton's rings installing plate support frame; the microscope is arranged on the microscope installing frame; an angle regulating knob of the microscope is connected with a coaxial microscope regulating wheel hub; a microscope angle regulating scale camera, a wheel hub rotating angle camera and a microscope eyepiece camera are installed; a step motor is arranged on the motor installing frame, and is connected with the microscope regulating hub through a belt. The network Newton's rings experiment instrument has the advantages that through the arrangement of the motor used for driving the microscope regulating wheel hub and the network camera, the remote experiment is realized; the experiment efficiency is improved; a semiconductor laser light source is used for experiment; clean single-set Newton's rings images are obtained; in addition, the light source service life is long; the cost required for always equipment switching-on in the remote control experiment is reduced.

Description

technical field [0001] The invention relates to the field of experimental devices, in particular to a network Newton ring experimental instrument based on a laser collimator. Background technique [0002] Newton's ring, also known as "Newton's ring". In optics, Newton's ring is a thin film interference phenomenon. It was first observed by Newton in 1675. Put a plano-convex lens with a large radius of curvature on a glass plate, and illuminate the lens and glass plate with monochromatic light, and you can observe some concentric rings with alternating light and dark. The ring distribution is sparse in the middle, dense at the edge, and the center of the circle is at the contact point. The center of Newton's ring seen from reflected light is dark, and the center of Newton's ring seen from transmitted light is bright. [0003] Traditional Newton's ring experiments are generally observed under a microscope using Newton's rings. The light source uses a sodium lamp, and the ex...

AI Technical Summary

Problems solved by technology

[0003] Traditional Newton ring experiments are generally observed under a microscope using Newton rings. The light source uses a sodium lamp, and the experiment can only be completed in the laboratory. When students find that the experimental data is insufficient and more experimental data are needed, they have to go back to Laboratory, and experiments cannot be performed remotely
