Asahi Spectra Co.,Ltd. (ASC) was founded in 1970 in Tokyo, Japan by 3 engineers. ASC has been developing a vacuum deposition technology such as ion assisted deposition (IAD) and ion beam sputtering (IBS) , which achieve hard coating, excellent durability for environment (humidity, low or high temperature, thermal shock or vacuum) and stability of spectral performance. By now our optical filters have contributed in various markets such as astronomy, semiconductor, biotechnology, education and so on.

Nowadays, customer requirements are becoming more complicated as optical innovation advances, and most requirements cannot be satisfied by just optical filter technology. So we have been trying to expand our field to optical instruments based on our over 40 years’ accumulated optical know-how as you can see how professional our optical instruments are.

Our integrated manufacturing process by both filter and instrument specialists is the most competitive advantage against "other only-optical-filter makers".
