Abstract

The invention discloses a desktop scanning electron microscope, the structure of which comprises an electron gun, a condenser mirror one, an electronic probe, a sample chamber, a base, a pull rod, an objective lens, a power cord, and a condenser mirror two. Open structure, the upper plate of the sample chamber is integrally formed with a round hole, the front side of the sample chamber is provided with a material inlet, the inner cavity is provided with an electronic probe, and the upper end of the electronic probe is provided with a power cord, which is connected by electricity , the first position of the condenser is provided with an electron gun, which adopts a built-in way to be installed up and down. The second condenser is located above the sample chamber. The present invention is provided with a pull rod. When the place needs to be moved, pull out the folding rod and move the handle along both sides. The parts are close together, and the base is lifted together, and the characteristics of the folding rod are used to avoid damage to the surface of the device, and it has a labor-saving effect when moving.

Description

technical field [0001] The invention is a desktop scanning electron microscope, which belongs to the technical field of electronic equipment. Background technique [0002] As scientific research and industrial production enter the nanometer field, people's requirements for microscopic technology and microscopic instruments are getting higher and higher, and the demand is also increasing. The desktop scanning electron microscope is different from the traditional large-scale scanning electron microscope. It is a brand-new design, which combines the advantages of optical microscope and traditional scanning electron microscope. [0003] The prior art discloses a desktop scanning electron microscope with an application number of 201520950740.1, which includes an electron gun, an objective lens, a diaphragm, and a sample carrier; the sample carrier is provided with a sample, and the electron beam emits an electron beam, and the electron beam Scanning the sample through the electr...
