Design of dual-band cold mirrors [PDF]

open access: yesScientific Reports, 2017
AbstractDual-band cold mirrors are designed based on third-order of 121.6 nm multilayers, and they are only composed of LaF3 and MgF2. The designed mirrors have a high reflectance at 121.6 nm and 280 nm, and a low reflectance in visible waveband; they also have a narrow bandwidth of 4 nm at 121.6 nm, and low sidelobe ripples of two stopbands.
