UVFS Broadband Dielectric Mirror, HR750-1100nm
Tuniu’s broadband dielectric mirrors are engineered for precision beam steering and reflection, making them ideal for use in continuous-wave and nanosecond laser systems. Featuring high-performance dielectric coatings, these mirrors deliver reflectivity greater than 99% for all polarization states-far exceeding that of conventional metal-coated mirrors—effectively reducing optical loss and enhancing overall system efficiency. Built on UV-grade fused silica (UVFS) substrates, these reflectors exhibit outstanding durability, an extremely low thermal expansion coefficient, and excellent abrasion resistance for reliable long-term performance.
We offer standard mirrors in round, elliptical, square, and D-shaped profiles with a variety of dimensions. For custom coatings and sizes, please contact us.
