Abstract
An optical device includes a first optical member and a second optical member formed of a medium having a refractive index greater than 1, and a multiple layer film section. The multiple layer film section has a structure in which at least two types of thin film layers namely a first thin film layer and a second thin film layer which has a refractive index higher than a refractive index of the first thin film layer, are stacked alternately. The first optical member and the second optical member are joined by an adhering means (an adhesive), and satisfy a predetermined condition. At the multiple layer film section, from a light incident, a light in a first wavelength band is let to be reflected, and a light in a second wavelength band which is shorter than the first wavelength band, and a light in a third wavelength band which is longer than the first wavelength band is let to pass (to be transmitted).
