OPTICAL MEMBER AND OPTICAL DEVICE COMPRISING THE SAME

摘要

Disclosed are an optical member and an optical device comprising the optical member. Specifically disclosed is an optical member whose surface is provided with an antireflective corrugation structure for suppressing reflection of incident light. Also specifically disclosed is an optical device comprising such an optical member. Namely, there is disclosed an antireflective structure excellent in environmental resistance. An optical member (antireflective structure) (1) comprises an optical member main body (10), and a protective film (20) covering the surface (10a) of the optical member main body (10) and transmitting incident light. A plurality of thin projected portions (12) are arranged on the surface (10a) of the optical member main body (10), thereby forming an antireflective corrugation structure (11) for suppressing reflection of incident light.
