Dielectric-Coated Plane Mirrors DLHS UV 248 nm
LINOS® Dielectric-Coated Plane Mirrors DLHS UV 248 nm are precision optical components for high-power, high-energy laser applications. Featuring a dielectric VUV high-power coating, these mirrors deliver exceptionally high reflection and ultra-low scattering losses, ensuring reliable performance in critical beam steering and deflection tasks. Optimized for beam deflection at a 45° angle of incidence, they provide precise 90° redirection of laser beams. Constructed on fused silica substrates with highly polished front and back surfaces, they maintain excellent thermal and dimensional stability.
With guaranteed reflection exceeding 99 % at 248 nm, DLHS mirrors combine high durability, optical precision, and stability under intense laser exposure, making them ideal for advanced laser systems, scientific research, and industrial applications requiring consistent, long-term performance.
