Optical component and method of manufacturing the same |
| abstract |
The present invention provides an optical member that can instantly confirm with the naked eye that there is no decentering even when a Fresnel lens or the like has a fine structure. The optical component of the present invention has an optical portion and a peripheral portion thereof, and has identification marks in the form of concavities and convexities that can recognize eccentricity at positions substantially symmetrical to each other on the front side and the back side of the peripheral portion. It is preferable that the above-mentioned two identification marks are mutually similar in shape, and one is 10 to 90% of the size of the other. |
