摘要： An anti-reflection coating is formed on an optical surface of an optical member 2 for reducing the amount of light rays reflected from the optical surface. For light rays in a wavelength range from 400 nm to 700 nm, the anti-reflection coating has a reflectance of 0.5% or less if the light rays are incident on the optical surface at angles within a range from 0 to 25 degrees, and it has a reflectance of 3.5% or less if the light rays are incident at angles within a range from 0 to 60 degrees.

摘要： In an imaging optical system 10, which comprises a plurality of optical members F and L1˜L12and an aperture diaphragm P, an anti-reflection coating 1 is provided selectively on the concave surfaces 2 and 3 of light-transmitting members (for example, negative meniscus lenses L1 and L2) that have concavities with respect to the aperture diaphragm P. The anti-reflection coating 1 comprises at least one layer or more made by a sol-gel method.
