Broadband Dielectric High-Reflection Mirror
High-performance broadband dielectric mirrors use multilayer dielectric films to form a highly reflective surface on an optical substrate, achieving near-100% reflectivity in specific bands. Compared with traditional metal-coated mirrors, they have the advantages of low absorption, strong thermal stability and precise phase control, making them the ideal choice for laser cavities, scientific research experiments, precision imaging and optical communication systems. Whether for narrow-linewidth lasers or high-power pulsed lasers, broadband dielectric mirrors work stably, reduce light loss and improve system efficiency.
