SEN, specialist in UV-radiation applied surface processing, modification, curing, sterilization and deodorization

Company History
1965	On July 1st, SEN Lights Corporation established its first premises in front of Senriyama's Kansai University with the intention of developing and producing "gas laser equipment".
1966	We developed prototypes for HeNe gas lasers, CO₂ gas lasers, CN lasers and Ar lasers, but the market was still not ready for their full-scale commercialization.
1973	For the first time in Japan, we succeeded in manufacturing rubidium lamps and resonance cells for frequency standardization, which were previously only available from other countries. We also developed the largest scale low pressure mercury lamp in Japan. From that time, we also become deeply involved in the field of ultraviolet research.
1975	We were awarded an Osaka prefectural subsidy for new technology and product development, and the developed the ultraviolet-ozone co-generation tube.
1976	We developed an ultraviolet and ozone water purifier (UZON R), which took us into the field of water purification.
1983	We acquired the rights to use and develop "UV ozone drain water oxidation equipment" developed by the Kanagawa Technical Analysis Center, thus deepening our capabilities and commitment to water purification technology.
1984	We received Osaka prefectural financing for high-technology and industrial promotion via Daiwa bank. R&D Theme: "Development of ultraviolet light source systems for semiconductor manufacturing" From this time, we began to explore the field of photo surface processing.
1985	Paid in capital was increased to JPY6,400,000.
1987	In conjunction with RAN Technical Service Co., Ltd., we incorporated SEN Engineering Co., Ltd., a photo surface processor marketing firm. In the same year, SEN Lights Corporation set up its Tokyo office and was awarded a technical development subsidy from the Ministry of International Trade and Industry. R&D Theme: "UV ozone removal of organic chlorine compounds in drain water"
1988	We established our main factory in the head office compound.
1995	Paid-in capital was increased to JPY25,600,000, and we issued JPY48,000,000 worth of convertible bonds.
1997	On March 1st, we opened our second equipment manufacturing plant just a short walk from head office.
