Technology used in Thin Film or Optical Coating Processes

There are two types of thin film coating processes – PVD (Physical vapour deposition) and CVD (Chemical vapour deposition). Thin film deposition is the process of creating and depositing thin film coatings onto a substrate material, to improve some element of performance. Thin film coatings are used to make products used in every-day life. Micro chips made in the semiconductor industry, ophthalmic lense used for reading glasses, car head lamps with aluminium coatings are examples of thin film depositions. Thin films are also used in a variety of space and defence applications. 


According to many experts, PVD and CVD coatings are harder and more resistant to corrosion than electroplating coatings since PVD coatings have such high impact strength, high-temperature threshold and excellent abrasion resistance. PVD is commonly used for applying coatings such as zirconium nitride, titanium, aluminium nitride, titanium nitride and chromium nitride. 


Buy the best quality product at competitive prices from HHV.

HHV has a wide variety of technical and optical offereings from the Thin Film Equipment and Optics divisions. HHV provides end-to-end, customized design services for thin film deposition systems, optical components and Thin-film Optical Coatings. Variations in coating compositions provide film properties suited for different applications. HHV offers systems and coating services through a range of deposition processes like Thermal Evaporation, Electron Beam Evaporation, Magnetron Sputtering, Effusion Cells, Ion Beam Sputtering, Glow Discharge, CVD, PECVD, Reactive Ion Etching and Atomic Layer Deposition. 


A surface can receive multiple layers of different coating materials to create a Thin Film Coating that completely protects and enhances the underlying part. Thin film coatings have to take place in vacuum to keep contamination low and uniformity high.


To meet the changing needs of the thin-film coating and equipment sector, HHV offers high-quality products for it’s customers. HHV manufactures dichroic coated optics, laser filters, narrow band interference filters, hybrid micro circuits, periscope prisms, thin film heaters and infrared optics for a variety of applications in industrial, space and defence technologies.
