Metal Coating
[Metal film]
A metal film is a metal film on a substrate (glass, plastic, metal, etc.).
Metal film deposition method
A film that has been deposited. The metal film is formed by plating or painting.
We offer high-performance and high-quality films by vapor deposition.
Doing. Because the deposition method can control the film thickness with high accuracy,
Transmits part of incident light as well as total reflection mirror coating
Half mirror coat can also be formed. Also, except for some metals,
Since it is not necessary to heat the substrate, it is possible to form a film on a plastic substrate.
is.
Usage
Applications range from precision optical components to decorative items, and the desired performance and
We propose the most suitable film type according to the cost and durability.
(1)Aluminum (Al)
The best combination of high reflection characteristics and low cost
One of the popular metal films.
Metal film alone lacks corrosion resistance and scratch resistance
Therefore, a dielectric transparent protective film (SiO) is applied to the surface.
(2)Chromium (Cr)
Reflectance is lower than Al, but low cost
High durability (corrosion resistance and scratch resistance)
One of the most popular metal films.
Because durability can be secured sufficiently with a single metal film,
Widely used for decoration as well as optical applications
It has been done. Also like Al
Also suitable for precise film thickness control and transmittance
And half with arbitrarily designed ratio of reflectance
Mirror coat can also be created.
(3)Gold (Au)
In order to show extremely high reflectance in the infrared region,
Used for optical equipment using infrared rays.
Corrosion resistance is extremely good due to the characteristics of Au.
Since the film hardness of a metal film alone is low,
When directly touching or wiping with cloth,
Attention should be paid to scratches on the membrane surface.
A dielectric transparent protective film (SiO) is applied to the surface.
Laminate to improve scratch resistance to some extent
can do.
