Abstract
A dichroic mirror includes a substrate and a dielectric multilayered film formed on a surface of the substrate. The dielectric multilayered film includes a first period layer with a structure represented by a formula (0.7H1.4L0.7H)and a second period layer with a structure represented by a formula (2HμL)in order from the substrate side. Wherein H represents a high refractive index layer and L represents a low refractive index layer, H and L are set at ¼ lambda of a reference wavelength associated with the film, μ is a coefficient of the L, and the superscript represents the number of repetitions of the structure, enclosed by the parentheses, used in the correspond first period layer or second period layer.
