The high reliability of vacuum deposition technology and the diversity of optical products that arise from it.
Vacuum deposition is a film formation technology that involves heating the deposition material in a high vacuum to vaporize it. The vaporized material, now in gas form, collides with and adheres to a substrate, resulting in the formation of a deposited thin film. This principle is similar to when a plate is brought over steam that is boiling and evaporating, causing the evaporated water to adhere to the plate. By varying the combinations of refractive index, thickness, and number of layers of dielectric and metallic deposition materials, it is possible to control the transmission, reflection, and absorption of light (ultraviolet, visible, and infrared). 【Features】 ■ Capable of film formation on glass, plastic, film, metal, etc. ■ Deposition materials include metal oxides (ZrO2, Al2O3, TiO2, SiO2, etc.) and metals (Al, Cr, Ti, Sn, Au, Ag, etc.) ■ Use of continuous vacuum deposition equipment enhances quality and productivity ■ Film formation in high vacuum improves the adhesion and quality of the deposited film *For more details, please download the PDF or feel free to contact us.

basic information
【Deposition Methods】 ■Resistance Deposition This type of evaporation source involves placing the deposition material on a resistance heating board, where the heat generated by the board's resistance melts and evaporates the deposition material. ■Electron Beam (EB) Deposition An electron beam is used to irradiate the deposition material with focused electrons. By focusing the electrons, the surface of the deposition material reaches temperatures of 1000°C to 3000°C, causing it to melt and evaporate. Our company primarily uses electron beam deposition. *For more details, please download the PDF or feel free to contact us.
