Physical light transmission device

Abstract

The invention discloses a physical light transmission device. The device comprises a slide rail, a light box support frame, a light box and a convex lens support frame. The light box support frame is arranged on the upper part of the front end of the slide rail. The light box is arranged on the upper end of the light box support frame. The convex lens support frame is arranged on the upper end in the middle part of the slide rail. A convex lens is arranged on the upper end of the convex lens support frame. A laser range finder is arranged on the lower end of the side face of the light box support frame. A screen support frame is arranged on the upper part of the back end of the slide rail. A screen is arranged on the upper end of the screen support frame. A light reflection sheet is arranged in the middle part of the side face of the screen support frame. A power supply switch is arranged on the front end of the side face of the slide rail. A display screen is arranged in the middle part of the side face of the slide rail. A control panel is arranged in the middle part of the side face of the slide rail. A charging port is arranged in the back end of the side face of the slide rail. A controller is arranged on the lower surface of the slide rail. The beneficial effects are that compared with a traditional light transmission device for a physical test, the provided light transmission device is characterized in that measurement data is quite precise, and the device is high in automation degree, quite simple to operate, high in creativity and convenient to adjust.

Description

technical field [0001] The invention relates to a physics experiment teaching device, in particular to a physical light-transmitting device. Background technique [0002] In physics teaching, because the knowledge in books is relatively abstract, it is difficult for students to fully understand it. Some experiments are often needed to help students deepen their understanding. The device uses a ruler to measure the distance between the light source, the convex lens, and the screen, and moves the relative positions of the three by hand. This experimental method has a large measurement error, and moving the position of the convex lens by hand is easy to make The tilt of the convex lens affects the experimental results, so it is necessary to design a new type of light-transmitting device for fully automatic laser ranging physical experiments to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a physical light-tran...
