Vacuum Deposition Method |
Principle of Vacuum Deposition
It is the same image that waterdrop is stuck on a lid when water in a pot is heated.
The phenomenon that water vapor is stuck is applied to the technology of vacuum deposition.
If the coating material were heated and vaporized by electric gun etc., the air would block the vaporized coating material from reaching to substrate.
To apply the vaporized coating material on substrate, the coating material is vaporized in the vacuum environment, and it is the vacuum deposition method.
Our products, Lequa-Dry and RefColor are applied by vacuum deposition method.

Anti Reflection Coating (AR Coating) |
Principle of Anti Reflection Coating
Anti Reflection Coating is called as “AR Coating”.
It is the coating to reduce the reflection upon surface of plastic and glass by interference* of lights.
The suitable coating to each substrate and the customized coating to meet the requirement from customers are available.
*interference : phenomenon that light wave is enhanced and reduced each other by overlapping.
Anti reflection function occurs by offset of each wave of lights.
