0399212-111
[DEFINITION]
A micro-lens structure resembling flattened out narrow rings.
[DESCRIPTION]
As a micro-lens that has low aberrations, high efficiency, and high
numerical aperture (NA), the micro-Fresnel lens is under research and development. The lens
realizes a high NA by a single lens and is manu-factured by reproduction of an original lens pattern,
which has been drawn by electron beam lithography on a glass substrate.
