T-BBD05-E01 - Ø1/2" Broadband Dielectric D-Shaped Mirror, 350 - 400 nm
T-BBD05-E01 - Ø1/2" Broadband Dielectric D-Shaped Mirror, 350 - 400 nm
E01-Coated Broadband Dielectric D-Shaped Mirrors offer >99% average reflectivity over the 350 - 400 nm spectral range. Although broadband dielectric 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.
