Movable type laser reflection, laser refraction and lens imaging demonstration combined device and using method thereof

Abstract

A movable type laser reflection, laser refraction and lens imaging demonstration combined device comprises a movable type semiconductor laser transmitter, an optical module, a teaching aid and a magnetic demonstrating board, wherein the optical module and the teaching aid are matched with optical experiments in use. The movable type semiconductor laser transmitter comprises a semiconductor laser transmitter I capable of emitting a beam of light or / and a semiconductor laser transmitter II capable of emitting two beams of light. The bottom of the semiconductor laser transmitter I, magnetic bases are installed at the bottom of the semiconductor laser transmitter II and the bottoms of the optical module and the teaching aid matched with the optical experiments in use. The magnetic demonstrating board is a flat board capable of sucking the magnetic bases. When the device is used, the movable type semiconductor laser transmitter and the optical module and the teaching aid matched with the optical experiments in use are sucked on the magnetic demonstrating board through the magnetic bases and can be moved optionally. The device can perform more than 50 optical experiments including light rectilinear propagation, light reflection, light refraction, lens imaging law, light interference, light diffraction and the like.

Description

technical field [0001] The invention relates to a teaching demonstration device, in particular to a combination device for optical reflection and refraction lens imaging demonstration for teachers' teaching or students' experiments. Background technique [0002] At present, in middle school laboratories, the helium-neon laser assembly 801 used for the demonstration of light reflection and refraction and the demonstration of lens imaging rules is fixed at the lower end of the teaching board, and the light passes through the exit hole 802 and shoots vertically to the three dielectric films fixedly installed at the upper end. On the beam reflector 803, the angle of the outgoing light is changed by turning the reflector angle adjustment knob 804 (see Figure 8 ). Since the beam exit position is fixed, the movement of the beam position is limited, the lens 805 and other optical tools are fixed through the handle insertion hole 806, and various optical paths cannot be flexibly for...

AI Technical Summary

Problems solved by technology

Since the beam exit position is fixed, the movement of the beam position is limited, and optical tools such as the lens 805 are fixed through the handle insertion hole 806, which cannot flexibly form various optical paths; and after a beam of light is divided into three beams, one is dimmer than the other, and the experimental results bad
