摘要
A diffractive optics element includes a substrate configured of a sapphire substrate and a diffractive optics structure, provided on the substrate, that forms an image when a laser beam is incident thereon. The diffractive optics structure has a diffractive optics portion, and the diffractive optics portion has a base material and a diffractive optics layer disposed on the base material. The thickness of the base material is no greater than 20 μm.
