Title:
REFLECTIVE TYPE IMAGING ELEMENT AND OPTICAL SYSTEM, AND METHOD OF MANUFACTURING REFLECTIVE TYPE IMAGING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/021451
Kind Code:
A1
Abstract:
A reflective type imaging element (1) comprises: a first reflective type element (11); and a second reflective type element (21) arranged on top of the first reflective type element. The first reflective type element and the second reflective type element respectively have a multi-layer structure in which a plurality of unit reflective type elements are laminated. The plurality of unit reflective type elements respectively have: a transparent section (1111); a reflective layer (1113); and an optical attenuation layer (1115) arranged between the transparent section and the reflective layer. The plurality of unit reflective type elements include two unit reflective type elements which are two mutually adjacent unit reflective type elements arranged so that the transparent section of one unit reflective type element and the reflective section of the other unit reflective type element are adjacent. The direction of lamination of the plurality of unit reflective type elements in the first reflective type element and the direction of lamination of the plurality of unit reflective elements in the second reflective type element are mutually orthogonal.
