回折格子の製造方法

Document Type and Number:

Japanese Patent JP5266059

Kind Code:

B2

Abstract:

An optical diffraction grating (10) is produced by providing a mold (50) having a plurality of inclined grooves (58), which have a small clearance angle (γ). The mold (50) is covered by a curable material (M1). Said material is subsequently cured, i.e. hardened, and separated from the mold (50) to provide the diffraction grating (10). The inclined orientation of the grooves (58) allows expansion or contraction of the grating during the curing and separation steps such that the probability of mold breakage may be reduced. The inclined orientation of the grooves may also facilitate the separation of the grating (10) from the mold (50).
