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)
Features
We can produce highly durable anti-reflection films with DLC coating (hard carbon film; diamond-like carbon).
The company’s unique coating using a plasma CVD method combines two features: high transmittance rates and high durability in the mid-infrared region (MIR).
We can coat Ge, Si, quartz, glass, chalcogenide and other substrate materials.
In addition, we can work not only with flat plates, but also lens materials, so please consult with us about your needs.
Applications
Infrared image element windows, combined lens for optical systems using infrared, window material for CO2 laser processing machine, etc.
Example characteristics
High transmittance rate
DLC is transparent in the mid-infrared region (MIR) so we can obtain anti-reflection film with high transmittance for Ge and Si substrates.
High durability
We can obtain a film surface with high hardness and excellent wear resistance for use as a protective film on the outermost layer.
In addition, it also has excellent moisture and salt water resistance.
Humidity resistance: 85・C / 85%Rh 600Hr
Peeling resistance: MIL-C-48497A 4.5.3.1
Salt water resistance: 85・C / 5wt% / 24Hrs
Maximum filmable size: φ400
