High Reflective 350-400m,400-750nm Dielectric HR Coating Broadband Coatings Laser Dielectric Mirrors

High Reflective 350-400m,400-750nm Dielectric HR Coating Broadband Coatings Laser Dielectric Mirrors

Our broadband dielectric reflective mirrors cover three core spectral bands: visible light, near-infrared (NIR), and infrared (IR). Designed to reroute light beams effectively, they help miniaturize optical assemblies and cut overall equipment footprint. These optical reflectors serve beam steering tasks requiring consistent high reflectance across broad wavelength ranges within visible, NIR and IR spectrums. As a professional optical manufacturer, Wavelength Opto-Electronic supplies premium broadband dielectric mirrors engineered with ultra-flat surface profiles, minimal stray light scattering and outstanding reflectivity performance.
