| titleOfInvention | Diffraction optical element and optical head using the same |
| abstract | Diffraction that emits substantially zero-order diffracted light when light having a wavelength of 0.35 μm to 0.45 μm is incident, and emits first-order diffracted light when light having a wavelength of 0.6 μm to 0.7 μm is incident An optical element is provided.n n n It is a rotational optical element provided with the board | substrate 1a and the grating part 2a formed on the board | substrate 1a. The cross section of the grating portion 2a is substantially a step shape of any of four, five, or six levels, and the light 3 of the first wavelength λ1 satisfying 0.35 μm ≦ λ1 ≦ 0.45 μm is incident. In this case, substantially diffracted light 6 of the 0th order is emitted, and when the light 4 of the second wavelength [lambda] 2 satisfying 0.6 [mu] m? 7) Exit. |
