4 Different Coating Technologies We Applied
At YUDI, we combine different coating technologies in production to meet various as much as possible while considering your precision, budget, and delivery needs.Our optical coating technologies include: EBE coating，IBS coating, IAD coating and APS coating tech.
Electron Beam Evaporation
Electron Beam Evaporation (EBE) utilizes an electron beam to sublime a source material into vapor, which is then deposited onto a substrate. Operating under high vacuum conditions, EBE is ideal for producing high-quality optical coatings. It finds applications in optical lenses, laser lenses, and thin film filters.
Ion Beam Sputtering
Ion Beam Sputtering (IBS) employs an ion beam to accelerate sputtered materials, creating high-quality, dense films. It is well-suited for precision optical components like interference filters, concave lenses, and mirrors. In ion-assisted electron beam deposition, targeted ions enhance coating adhesion and density on optical surfaces.
Ion Assisted Deposition
IAD is a physical vapor deposition (PVD) technology and its main advantage of this technology is to improve the density and adhesion of the film, thereby improving the optical performance and durability of the film. Therefore, it is often used to prepare anti-reflective coatings and laser lenses
Advanced Plasma Sputtering
APS represents the latest evolution of thin film coating technology. Its core feature is hot cathode DC glow discharge plasma instead of traditional ion beams for depositing coating materials. It has been a more efficient and precise film deposition while maintaining the versatility and stability of optical performance.
