Optical Coating Machine and Optical Coating
In the process of optical coating, it is often necessary to measure the partial pressure and analyze gas, which requires the mass spectrometer. In 1950, Mr.Tretner (Tretner) invented the line vibration mass spectrometer, as a pure electric field mass spectrometer, the probe size is small, which can be used in the rapid change process of pressure detection; in 1962, Tretner Analyze the line-vibration mass spectrometer from the point of view corresponding to the optical system, and deduce the resolving power expression of the line-vibration mass spectrometer; in 1964, Teubner (Tuoibner) proposed another working method of the device, even if The amplitude period of the potential well is changed, so that the frequency of the modulation voltage is fixed to ensure that the amplified signal is selected.
Vacuum coating machine mainly refers to a type of coating that needs to be carried out under a higher vacuum, including vacuum ion evaporation coating machine, magnetron sputtering coating machine, MBE molecular beam epitaxial coating machine and PLD laser sputtering deposition coating machine, etc. It is mainly divided into evaporation and sputtering. In the vacuum coating equipment, what needs to be coated is referred to as the substrate, and the plated material is used as the target. The substrate and the target are in the same vacuum chamber. Evaporation coating is generally to heat the target material to evaporate the surface components in the form of radicals or ions, and settle on the surface of the substrate, forming a thin film through the film forming process. Vacuum coating machine for sputtering coating can be simply understood as using electrons or high-energy lasers to bombard the target material, and the surface components are sputtered out in the form of radicals or ions, and finally deposited on the surface of the substrate, undergoing the film forming process. Finally, a thin film is formed. The furnace body can be made of stainless steel, carbon steel or a combination of double
Layer water cooling structure.
Choose different specifications and types of coating equipment according to the process requirements. The types include resistance evaporation vacuum coating equipment, electron beam evaporation vacuum coating equipment, magnetron sputtering vacuum coating equipment, ion plating vacuum coating equipment, magnetron reactive sputtering vacuum coating equipment, Hollow cathode ion plating and multi-arc ion plating, etc. The operating modes of the fixture include rotation, revolution and revolution + rotation. The user can put forward corresponding requirements according to the size and shape of the piece. The speed range and accuracy of rotation: ordinary adjustable and frequency conversion speed control.
