| titleOfInvention | Optical parts for laser light |
| abstract | In the optical head device using a light source including a blue semiconductor laser, the durability is reduced when an optical component using a material optimized for use in an optical path of a laser beam for reproducing and recording CD and CVD is used. It is a problem to suppress the problem. The 1st transparent board | substrate 1 and the 2nd transparent board | substrate 2 correspond to the uneven part 5 which consists of a polymeric liquid crystal between them, the filling adhesive 7 which fills the unevenness, and 1/4 of a use wavelength The phase plate 6 having a retardation is sandwiched. An inorganic optical multilayer film 3 is formed on the entire surface of the first transparent substrate 1 on the side opposite to the uneven portion 5, and the surface of the entire surface of the second transparent substrate 2 on the side opposite to the uneven portion 5. The inorganic optical multilayer film 4 is formed into a film. By forming the optical multilayer film 4, the light of 400-410 nm which injects into the 2nd transparent substrate 2 is reduced to 20% or less of the intensity of the light which injects into an optical multilayer film. |
