Dielectric-Coated Plane Mirrors DLB UV 230-400 nm
LINOS® DLB UV 230–400 nm Dielectric-Coated Plane Mirrors are engineered for high-power and high-energy laser applications, combining durability with superior optical performance. Featuring a dielectric laser coating, these mirrors deliver high reflectivity across a broad UV range and maintain excellent performance over angles of incidence from 0° to 45°. Optimized for beam steering at a 45° angle of incidence, they provide precise 90° beam deflection while minimizing scattering losses. The polished back surface enhances mechanical stability and handling, reducing stress and potential damage during installation and operation.
Built on a fused silica substrate, these mirrors provide excellent thermal and mechanical stability. Their low-loss reflection, durability, and precise beam control make them well-suited for demanding UV laser setups, delivering consistent performance in research and industrial environments.
