Features
We coat metal films such as gold, silver and aluminum on various substrates. Generally, metal films are used as mirrors in various optical systems. Metal films scratch easily, and are scratched by hand cleaning. In addition, since they oxidize, depending on the environment, they are generally given an SiO2 protective film at the final layer.
The company can coat not only flat substrates, but also large area substrates and substrates of different shapes.
We also do metallization processing for soldering that is suitable for vacuum sealing, which is required to preserve the high sensitivity of infrared image sensors.
Applications
Metal thin-film mirrors, solder-sealing
We have a track record in coating with various kinds of metal.
Gold (Au), silver (Ag), aluminum (Al), copper (Cu), chromium (Cr), platinum (Pt), nickel (Ni), titanium (Ti), tungsten (W), molybdenum (Mo), tantalum (Ta), hafnium (Hf), niobium (Nb)
特性例
Gold mirror for Near-infrared
Gold mirrors have high reflectivity in a wide range of the near-infrared to infrared regions.
Aluminum mirror
Aluminum mirrors can be used in the visible to infrared range.
They have reflectivity of about 85% in visible light and about 90% in the near-infrared and infrared regions.
