Successfully tested on board the NASA Space Shuttle!
Among glossy metals, silver plating is considered to have good reflection across a wide range of wavelengths. However, silver plating tarnishes quickly in the air. To solve this problem, Mitsuya developed high-reflective gold plating. Compared to our conventional gold plating, the reflectivity has improved by 4-6%. High-reflective gold plating is widely used in various applications, such as: - Marking on wafers during semiconductor manufacturing processes - Pulse laser welding - Laser cutting machines Astronaut Koichi Wakata conducted experiments to create alloys using an imaging furnace installed on NASA's Space Shuttle. The reflective mirror of this imaging furnace uses the high-reflective gold plating developed by Mitsuya. This mirror is the most critical component for the imaging furnace.

basic information
Among glossy metals, silver plating is considered to have good reflection across a wide range of wavelengths, but silver plating tarnishes quickly in the air. Mitsuya developed a high-reflective gold plating to solve this problem. Astronaut Koichi Wakata conducted experiments to create alloys using an image furnace installed on NASA's Space Shuttle. The high-reflective gold plating developed by Mitsuya is used on the mirrors of this image furnace. These mirrors are the most essential components for the image furnace.

Applications/Examples of results
【Applications】 High reflectivity, good soldering and bonding properties, low contact resistance - Space-related - Marking on wafers during semiconductor manufacturing processes - Pulsed laser welding - Laser cutting machines, etc. 【Examples of Achievements】 Using a reflector concentrator with halogen bulbs, we aimed to create ingots of compound semiconductors. For an experiment to be conducted in space, we were looking for a supplier that could provide high-quality plating with good reflectivity on ultra-precision aluminum parts. The product was used in Dr. Mori's space experiment, which was successful. It is also used in a wide range of other fields.
