Title:
BROADBAND REFLECTING MIRROR
Document Type and Number:
WIPO Patent Application WO/2010/013389
Kind Code:
A1
Abstract:
Provided is a broadband reflecting mirror that has a high reflectance in the band with wavelengths ranging from 400nm to 2,500nm, heat resistance, and flaw resistance.  A broadband reflecting mirror (1) for reflecting light in a band with wavelengths ranging from 400nm to 2,500nm, is provided with a first reflecting stacked film (3) in which a first high refractive index material layer and a first low refractive index material layer are stacked alternately to reflect light with a band on a short wavelength side in the band with wavelengths ranging from 400nm to 2,500nm, a second reflecting stacked film (4) in which a second high refractive index material layer and a second low refractive index material layer are stacked alternately to reflect light with a band on a long wavelength side in the band with wavelengths ranging from 400nm to 2,500nm, wherein the broadband reflecting mirror is characterized in that the first reflecting stacked film (3) is arranged on the incident side of the light, while the second reflecting stacked film (4) is arranged at a position from which the light penetrating the first stacked film (3) can be reflected.
