The 21st century is the "Era of Light." Optical communication, displays, and optical storage media are evolving, and light is becoming increasingly essential for information transmission. For example, it is said that by processing signals using only light without converting them to electrical signals, the processing speed can increase by a million times. Okamoto Glass Co., Ltd. is advancing research on glass materials that will serve as optical devices to put such theories into practical use. To enrich the era of optoelectronics, we will further refine our accumulated technological and development capabilities and continue to provide products and services that impress our customers as a research and development-oriented company that "scientifically studies light."

Traditionally, aluminum has been the common material used for reflective mirrors, but it has the issue of low reflectivity. Therefore, we developed a "silver mirror" using silver, which is the material with the highest reflectivity among metals. When 100% of light hits the mirror, aluminum reflects only 92%, while silver reflects 97%. Additionally, it has achieved durability equivalent to 20 years of outdoor exposure. We are currently offering technical documentation on High Silver. 【Features】 ■ Achieves a high reflectivity of 97%, the highest standard ■ Ideal for applications requiring high brightness, high output, and high saturation in industrial use ■ Durability equivalent to 20 years of outdoor exposure ■ Passes all tests for heat resistance, humidity, saltwater, and gas corrosion *For more details, please request documentation or view the PDF data available for download.
