Hitachi scanning electron microscope manufacturer gives you the basic structure of the analysis electron microscope: the ion beam used as the observation sample is sent out from the ray tube, and the ray tube is sent out by the electronic devices in the filament. Anodizing has an anodic oxidation on the gate, and there are many high voltages between the two sides, so that the ejected electronic devices will rush to the anodizing, and the sent electronic devices will go through the concentration of the electromagnetic lens and become an ion beam. When the ion beam is based on the sample, because the sample is too thin, the electronic devices that pass through will be different from each other. The different ion beams undergo the enlargement of the electromagnetic lens and become the image of the electronic device of the test product. In that way, the image is projected onto the display screen coated with luminous powder, and it can be observed with the human eye. In addition, you can also record the observation results by taking pictures. Because the ion beam passes over the sample, it is called an electron microscope.
Electron microscope manufacturers share the basic structure and imaging characteristics of electron microscopes
High power electron microscope
The electron microscope has its characteristics: it is also an electronic device created by the use of an ion beam gun, which is gathered into a small ion beam through an electromagnetic lens, and the ion beam is used to develop a scanner on the sample. When the ion beam impacts the test product, it accelerates the interaction between the electronic device and the test product, causing the test product to create a variety of Hitachi scanning electron microscope devices. In this electronic device, the main component used for imaging is secondary. Electronic devices have become larger after being collected, and the image of the test product appears on the display screen of the kinescope. Therefore, the ion beam is displayed on the sample scanner, so it is called an electron microscope.
Appropriate application of high magnification electron microscope and standard practical operation ensure the wear resistance and accuracy of equipment and equipment. Non-standard applications will cause insufficient measurement results of the instrument. High precision cannot succeed in further scientific research. Therefore, in the application of optics The microscope must also ensure the degree of damage to the equipment.
(1) Be very cautious in actual operation, and not have any strong postures. Autonomous disassembly and assembly of optical and electronic systems is not allowed.
(2) It is forbidden to directly touch a part of the laminated glass of the imaging lens of the optical microscope and the pressure surface of the test piece with your fingers. If dust falls on the camera lens, it will endanger the image quality and screen resolution of the optical microscope. At this time, first use the ear-washing ball to blow off the dust and sand, and then gently scrub with a cleaning cloth or brush to prevent the laminated glass of the camera lens from being scratched during the immediate cleaning, which will harm the actual effect of the application.
Frequently Asked Questions about Proper Application of Biological Microscopes
(3) Do not plug the power plug of the light bulb (6~8V) of the optical microscope to the 380V power plug immediately. It should be plugged into the transformer, otherwise it will burn the bulb immediately. The power should be cut off immediately after the observation.
(4) The posture should be slow when turning the coarse adjustment (or adjustment) handle, and the actual operation should be terminated immediately when a certain type of obstruction is encountered, and the specific instructor should be reported to search for reasons. Forced rotation cannot be used, otherwise the parts will be destroyed.
