High Reflective Gold Plating

sample of High Reflective Gold Plating

As a bright metal, it has been known that silver plating has a high reflectance in a wide wavelength range.
However, silver plating is easy to discolor in air. Therefore, Mitsuya developed a High Reflective Gold plating to solve this problem. Astronaut Mamoru Mohri who is also a scientist was tasked with the experiment to make an 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 aspect to determine the performance of the image furnace.
The reflectance was improved by as much as 4-6%, compared 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.
Our High Reflective Gold plating has been used in other products as well. For example, the plating has been used for the following products.
・Wafer marker for semiconductor production
・Pulse laser welder
・Laser trimming machine
