The Development of aspheric elements using replication process

비구면 광학소자의 복제기술 개발

Aspheric optical elements can provide an advantage in the design of optical system that require high performance and small size. The main disadvantage of high volume production of aspheric optical elements is very high cost. In this paper, we suggest new technology of high volume production process using replication process. The replication is a thin film of UV cured resin on a solid substrate blank(polymer substrate) with aspheric surface.
