摘要： An optical element having an antireflection effect includes an incident plane and an emission plane and a conical microstructure formed on at least one plane of the incident plane and the emission plane. The conical microstructure includes a first structure formed of a plurality of conical microprojections with an average height H1 and a second structure formed of a plurality of conical microrecesses with an average height H2. The average height H1 satisfies an inequality H1≦1/3*λ/n and the average height H2 satisfies an inequality H2≦1/3*λ/n. An average pitch P between the first structure and the second structure satisfies following conditions: H1/2≦P≦1/3*λ/n, and H2/2≦P≦1/3*λ/n, in which the use wavelength is defined as X and the refractive index relative to the use wavelength is n.

摘要： An optical element using visible light from wavelengths λS to λL (λL>λS), is formed of a translucent material having refractive indexes nS and nL, respectively, for light having the wavelengths λS and λL. The optical element includes an incident face; an exit face; and a micro convexo-concave structure used as an anti-reflection structure (ARS), being formed at least one of the incident face and the exit face. An average distance P between adjacent micro convexo-concave structures satisfies condition (1) P≦0.8·λS/nS. Dimensionless parameters mS and mL satisfy condition (2) 0.8≦mS≦1.1 and condition (3) 0.8≦mL≦1.1. The parameters mS and mL, an average height H, the wavelengths λS and λL, and the refractive indexes nS and nL of the micro convexo-concave structure satisfy condition (4) mS·λS/(2·nS)≦H≦mL·λL/(2·nL).
