High reflective Gold plating

High reflective Gold plating

As a bright metal, it has been known that silver plating have a high reflectance in a wide wavelength range.
However, silver plating is easy to discolor in the air. Therefore, Mitsuya developed a High reflective Gold plating to solve this problem. Astronaut Mamoru Mohri who is also an scientist was performed to the experiment to make the alloy in space, by using the "image furnace" installed at the space shuttle Endeavour of NASA.
They adopted Mitsuya's gold plating as a reflective mirror for the image furnace. The reflective gold mirror was the most important part to determinate the performance of the image furnace.
The reflectance is improved by about 4-6%, comparing to our bright gold-plating. The high reflective gold plating of Mitsuya is the most advanced technology on the high performance mirror for an image furnace.
High reflective Gold plating has been used in the other products widely. For example, this plating is used for the following products.

  • Wafer marker for semiconductor production
  • Pulse laser welder
  • Laser trimming machine
