| titleOfInvention | Optical component for laser beam |
| abstract | The present invention is to suppress deterioration of durability at the time when an optical component using a material optimized to be used in an optical path of a laser beam for performing reproduction/recording for a CD and a DVD is used in an optical head device using light sources including a blue semiconductor laser. A first transparent substrate 1 and a second transparent substrate 2 sandwich and hold therebetween a concave-convex portion 5 comprising a polymer liquid crystal, a filling adhesive 7 for filling the concave-convex, and a phase plate 6 having a retardation corresponding to ΒΌ of a wavelength used. An inorganic optical multilayer film 3 is formed on the whole surface of the first transparent substrate 1 , on the side opposite to the concave-convex portion 5 , and an inorganic optical multilayer film 4 is formed on the whole surface of the second transparent substrate 2 , on the side opposite to the concave-convex portion 5 . The formation of the optical multilayer film 4 reduces the intensity of light of 400 to 410 nm which enters the second transparent substrate 2 to 20% or less of that of light which enters the optical multilayer film. |
