Anti-Reflection Coating Machines
Anti-reflection coating machines are specialized equipment used to deposit thin, transparent coatings on optical components like lenses, mirrors, and displays to reduce reflection and increase the transmission of light. These coatings are essential in a variety of applications, including optics, ...Read more -
Introduction to Filter Performance Specifications-Chapter 2
Since filters, like any other man-made product, cannot be manufactured to exactly match the specifications of the manual, some allowable values must be stated. For narrowband filters, the main parameters for which tolerances should be given are: peak wavelength, peak transmittance, and bandwidth,...Read more -

Introduction to Filter Performance Specifications-Chapter 1
Filter performance specifications are necessary descriptions of filter performance in a language that can be easily understood by system designers, users, filter manufacturers, etc. Sometimes the filter manufacturer writes the specifications based on the achievable performance of the filter. Some...Read more -
Magnetic Filtration Vacuum Coating systems
Magnetic filtration in vacuum coating systems refers to the use of magnetic fields to filter out unwanted particles or contaminants during the deposition process in a vacuum environment. These systems are often employed in various industrial applications like semiconductor fabrication, optics, an...Read more -
Metallic Film Reflector Coating
Silver was once the most prevalent metallic material until the mid-1930s, when it was the primary reflective film material for precision optical instruments, typically chemically plated in a liquid. The liquid chemical plating method was used to produce mirrors for use in architecture, and in thi...Read more -
Vacuum Evaporation Process
The vacuum vapor deposition process generally includes substrate surface cleaning, preparation before coating, vapor deposition, loading, after coating treatment, testing, and finished products. (1) Substrate surface cleaning. Vacuum chamber walls, substrate frame and other surface oil, rust, re...Read more -
Film Layer Evaporation Temperature and Vapor Pressure
Film layer in the evaporation source of heating evaporation can make the membrane particles in the form of atoms (or molecules) into the gas phase space. Under the high temperature of the evaporation source, the atoms or molecules on the surface of the membrane get enough energy to overcome the s...Read more -
PVD coatings: Thermal evaporation and sputtering
PVD (Physical Vapor Deposition) coatings are widely used techniques for creating thin films and surface coatings. Among the common methods, thermal evaporation and sputtering are two important PVD processes. Here’s a breakdown of each: 1. Thermal Evaporation Principle: Material is heated i...Read more -
E-beam Vacuum Voating
E-beam vacuum coating, or electron beam physical vapor deposition (EBPVD), is a process used to deposit thin films or coatings onto various surfaces. It involves using an electron beam to heat and vaporize a coating material (like metal or ceramic) in a high vacuum chamber. The vaporized material...Read more -
PVD coating technology in the mold application
China has become the world’s mold production base, mold market share of more than 100 billion, mold industry has become the basis of modern industrial development. In recent years, China’s mold industry to more than 10% of the annual growth rate of rapid development. Therefore, how to...Read more -
Meaning of vacuum pumping
Vacuum obtaining is also known as “vacuum pumping”, which refers to the use of different vacuum pumps to remove the air inside the container, so that the pressure inside the space drops to below one atmosphere. At present, in order to get the vacuum and commonly used devices including rotary vane...Read more -
The vacuum vapor deposition process
The vacuum vapor deposition process generally includes steps such as substrate surface cleaning, preparation before coating, vapor deposition, picking up pieces, post-plating treatment, testing, and finished products. (1) Substrate surface cleaning. Vacuum chamber walls, substrate frame and other...Read more -
An Introduction to Vacuum Coating
Why Use a Vacuum? Preventing Contamination: In a vacuum, the absence of air and other gases prevents the deposition material from reacting with atmospheric gases, which could contaminate the film. Improved Adhesion: The lack of air means that the film adheres directly to the substrate without air...Read more -
Thin Film Deposition Technology
Thin film deposition is a fundamental process used in the semiconductor industry, as well as in many other areas of materials science and engineering. It involves the creation of a thin layer of material on a substrate. The deposited films can have a wide range of thicknesses, from just a few ato...Read more
