We have added 'Gold Mirror (Au Reflection Coating)' to our standard inventory.
At Adachi New Industry Co., Ltd., we prepare standard stock items that are easy to verify in order to facilitate smoother product development for our customers. Gold mirrors (Au mirrors) are optical elements that use the precious metal "gold (Au)" as a reflective film material, exhibiting an extremely high reflectivity (>96%) in the infrared spectral range (800 nm to 2 µm). Please make use of them.
◆◆ Are you facing any of these issues?
- The performance varies significantly depending on the reflective wavelength range of the gold mirror, requiring technical judgment to select the most suitable specifications for the application.
- There are differences in quality parameters such as film thickness accuracy, uniformity, adhesion strength, and surface roughness, making selection difficult.
- Optical components using high-purity gold have complex manufacturing processes and are easily affected by material procurement.
- Price differences can be significant due to fluctuations in gold costs and the precision of manufacturing equipment, making simple price comparisons challenging.
- The wavelength range and incident angle characteristics may not match requirements, leading to risks and costs associated with reordering.
- It is difficult to find processing sources that can produce stable prototypes in small quantities.
