Vapor Deposition Materials

There are several methods to form thin films, but vacuum vapor deposition is most often used to form optical thin films. Vacuum vapor deposition is a method to produce vapor by heating and melting materials and deposit thin films from vapor. We use various materials to suit each required characteristic.

High refractive

Medium refractive

Low refractive

Functional material


Sputtering is a method to accelerate ionized molecules and atoms, bombard them with materials, and then deposit blown materials on substrates as thin films. The materials are called  target. The shape of the target is determined by the device like a rectangle or cylinder.In general, the bonding type target is used where the material is attached to the backing plate. Especially for cylindrical targets, in addition to bonding types, we also offer thermal spray types and integral molding types. We provide the best type for each target material.

Optical Communication Substrates

Recently expanding needs for communication depends on the technical advantage of lines to carry data. Optical communication is the system to play a key role. Particularly, filters to separate optical signs adopted in core systems connecting big cities require high stability. WMS substrate helps to produce these filters.
