DIFFRACTIVE OPTICAL ELEMENT AND IMAGING APPARATUS USING THE SAME

摘要

A diffractive optical element includes a first optical member, a second optical member, and a third optical member stacked on each other in this order in an optical axis direction. A diffractive surface including a plurality of raised parts is formed at an interface between the first and second optical members. The first and third optical members contact each other at part other than the raised parts.
