SOC began the research of coatings for dielectrics early, established coating technology for high-power lasers first in Japan, completed ultra high damage resistance UV mirrors far ahead of the international standard, and achieved other major accomplishments. It is called the "SOC of coating technologies" with these achievements. SOC executes strict quality evaluations using loss meters capable of measuring minute losses as small as 1 ppm, a laser durability evaluation system with excimer and YAG lasers, etc. SOC enjoys incomparable reliability as a leader in laser optics.

Making full use of very precise polishing technology according to substrate materials and original coating and evaluation technology based on rich experiences, SOC develops and manufactures high-performance and high-quality optics to meet customers' needs for vacuum UV and infrared rays.

Upon request, SOC provides OEM optical products for various optical equipment and systems developed and manufactured by customers. SOC's integrated processes from development to manufacturing enable short-term delivery to meet customer needs. With core technologies, including precision polishing, coating, and lasers as well as aberration correction and other optical design know-how accumulated through long experience, SOC provides high-quality optical systems. In particular, the company has made significant achievements and gained extensive experience in applied laser optical systems for laser processing machines and inspection/measuring instruments, infrared ray optical systems for safety/disaster prevention monitoring systems and non-contact temperature measuring equipment, optical systems installed in vehicles and airplanes requiring high environmental durability, etc.
