OPTICAL MEMBER, METHOD OF MANUFACTURING THE SAME, AND IMAGE DISPLAY DEVICE APPLYING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical member which is excellent in production efficiency and with which the desired optical member can be obtained at need and a method for manufacturing the same and an image display device applying the optical member.

SOLUTION: The 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.
