METHOD FOR MANUFACTURING OPTICAL ELEMENT

Document Type and Number:

WIPO Patent Application WO/2011/111409

Kind Code:

A1

Abstract:

A diffraction grating (7) is formed on the surface (6) of a base material (1) by a nano-imprinting method. The base material (1) is cut on a cutting surface (A) that intersects the surface (6) in the longitudinal direction of the base material (1). The base material (1) is cut on a cutting surface (B) in the longitudinal direction at a predetermined distance from the cutting surface (A). Thus, a cut piece (30) sandwiched between the cutting surface (A) and the cutting surface (B) is obtained from the base material (1). A plurality of optical elements are manufactured by cutting, at predetermined intervals, the cut piece (30) on the cutting surfaces that intersect the cutting surface (A) and the cutting surface (B).
