Beschreibung
Zusammenfassung:	It is possible to a variable spectroscopy device that has a plurality of coating layers facing each other at an interval and changes a transmission band of light passing through the coating layers by adjusting an optical path length between the coating layers, in which the coating layer is structured so that a change rate of a transmission bandwidth between two arbitrary transmission bands is smaller than a change rate of a central wavelength between the two transmission bands within a spectroscopy wavelength band for changing a transmission band.
