| titleOfInvention |
Fresnel lens and optical device provided with same |
| abstract |
Provided is a Fresnel lens capable of diffusing and diffusing high-quality light without unevenness without lowering the center roughness even when a semiconductor light source having excellent heat resistance and poor quality is used. The Fresnel lens of the present invention is a Fresnel lens having two or more prismatic shapes on its surface and includes a cured product of a curable composition containing an epoxy compound (A), passes through the center point of the Fresnel lens And the surface of the prism having the longest slope in the cross section when the Fresnel lens is cut from the plane perpendicular to the reference plane of the Fresnel lens is roughened. |
