Multifunctional microscope for physical teaching experiments

Abstract

The invention relates to the technical field of microscopes, and specifically relates to a multifunctional microscope for physical teaching experiments. The multifunctional microscope comprises an electron microscope system, a CPU, a TV camera control system, an external computer control system and a remote mobile control system. The multifunctional microscope provided by the invention is provided with a Bluetooth identification unit that can be connected with a smart phone, the mobile control can be monitored, the Bluetooth identification unit can be wirelessly connected with a CRT through a LAN network to realize remote control, a TV camera is provided to display a video below the microscope on a computer through a video processor, a quick automatic focusing unit of a miniature computer calculates the definition of an image, analyzes the defocus state of the image, and then sends a command and data to a singlechip through an RS-232 interface to control the step pitch and the steering of a z-axis step motor for focusing, automatic focusing can be realized, the multifunctional microscope disclosed by the invention can realize automatic focusing, the video of the microscope can be displayed on the computer to realize remote mobile control, and the creativity is very high.

Description

technical field [0001] The invention relates to the technical field of microscopes, in particular to a multifunctional microscope for physics teaching experiments. Background technique [0002] A microscope is an optical instrument composed of a lens or a combination of several lenses, and it is a sign that human beings have entered the atomic age. It is mainly used to magnify tiny objects into instruments that can be seen by human eyes. Microscopes are divided into optical microscopes and electron microscopes: Optical microscopes were first invented by Jansen and his sons in the Netherlands in 1590. The current optical microscope can magnify the object by 1600 times, and the minimum limit of resolution reaches 1 / 2 of the wavelength. The length of the domestic microscope mechanical barrel is generally 160 mm. Among them, Leeuwenhoek and the Netherlands have made great contributions to the development of microscopes and microbiology. membership. The microscope is one of th...

Problems solved by technology

[0003] In the above patent documents, since the loading platform is interlocked with the support rod through the tightening screw and the washer that pass through the side wall of the lower ferrule, when the inspection conditions change, the loading platform can be adjusted up and down without the need for height adjustment. The height of the inspection object only changes the structure, and there is a lack of technical solutions for how to provide a multifunctional microscope for physics teaching experiments with faster system operation, higher security and complete functions
