The mirror (5) includes a substrate (6) and a dielectric multilayer coating structure (7) formed on the substrate (6). The multilayer coating structure (7) includes two mirror-function layer portions (ML 1 , ML 2 ), each formed by a plurality of layers deposited one on another, and a cavity layer (C) that is arranged between the two mirror-function layer portions (ML 1 , ML 2 ), and which causes light (L) having a predetermined wavelength to resonate between the two mirror-function layer portions (ML 1 , ML 2 ). Further, a dispersion value with respect to the light (L) having the predetermined wavelength is in the range of -600fs 2 to -3000fs 2 and a reflectance with respect to the light (L) having the predetermined wavelength is in the range of 97% to 99.5%.
