OPTICAL SYSTEM AND EYEPIECE

摘要

An eyepiece (EL1) includes a first lens (L1) having a positive refractive power and a second lens (L2) having a positive refractive power which are arranged in this order from an object (O). A contact multi-layer diffractive optics (DOE) is arranged on an optical surface of the first lens (L1) or the second lens (L2). The contact multi-layer diffractive optics (DOE) includes a first optic element (51) having relief pattern and a second optic element (52) which is in contact with the surface of the first optic element (51) where the relief pattern is formed.
