Coating Process
Suitable coating processes are necessary to enhance production capability. Optorun optical thin film coaters are developed based on coating process requirements.Vacuum Coating
When coating materials are heated in vacuum, they are evaporated and formed as thin films on substrate surfaces. Such processes are called vacuum coating. High quality thin films are formed in vacuum by getting rid of impurities.Evaporation is a reliable and versatile method, being capable of coating various metallic and dielectric materials. Higher coating rate and good thin film distribution are obtainable by use of resisting and electron beam evaporators.
Ion Assisted Deposition
Ion assisted deposition (IAD)is to enhance thin film adhesion and quality. Energetic ions from ion sources hit thin films on substrates, lifting the packing density of such films. This is how quality thin films are formedThe tuning of electron beam evaporators and ion sources can be done independently, which makes easy to seek suitable process parameters, such as to deposit low-absorption or stress-free films. Unparallel production reliability and film properties are obtained in such a way with ion assisted deposition.
Ion assisted deposition is applied in OptorunSPOC series (Vacuum Deposition System for DWDM Filter) and OTFC series (Optical Thin Film Coater). The research is being made in Optorun to apply OTFC series to optical, energy, information, and other applications.
