OPTICAL MEMBER, METHOD FOR PRODUCING SAME, AND IMAGE DISPLAY EMPLOYING SAME

摘要

A highly versatile optical member machined into a circular shape for eliminating the effect of optical axis unique to optical members is disclosed which is capable of facilitating stock control without lowering production efficiency. An optical member having a higher degree of freedom in design can be provided by employing such a production method wherein a long optical member is machined into a circular shape and then the circular optical member is machined into a desired shape so that the optical axis can be adjusted finely even after machining of the long optical member. ® KIPO & WIPO 2007
