본문내용

A dichroic mirror comprises a transparent substrate, a dielectric multilayer structure formed thereon. The dielectric multilayer structure includes a main multilayer structure comprised of high refractive index layers and low refractive index layers formed alternately, each layer having an optical thickness of lambda over 4 where lambda is the designed central wavelength, a first transmittance regulating film provided between the main multilayer structure and the transparent substrate, and a second transmittance regulating film provided on the other side of the main multilayer structure. The first and second transmittance regulating films typically have a three or four layer structure of intermediate refractive index layers and low refractive index layers formed alternately. The intermediate refractive index layers have a refractive index lower than but close to that of the high refractive index layers.
