E02-Coated Broadband Dielectric D-Shaped Mirrors offer >99% average reflectivity over the 400 - 750 nm spectral range. Although broadband coatings offer smaller operating wavelength ranges than metal mirrors, they typically yield higher reflectivity in those ranges than their metallic counterparts.
The plot to the right shows the measured reflectivity of this coating as a function of wavelength. The shaded region denotes the range over which we recommend using these optics. Data was obtained using at a 45° angle of incidence.
