Dielectric-Coated Plane Mirrors DLHS UV 266 nm
LINOS® Dielectric-Coated Plane Mirrors DLHS UV 266 nm are precision optical components engineered for high-power and high-energy laser applications. Featuring a dielectric VUV high-power coating, these mirrors deliver exceptionally high reflection with ultra-low scattering losses, ensuring reliable performance in critical beam steering and deflection tasks. Optimized for 45° angles of incidence, they provide precise 90° beam deflection and can also function as dichroic or longpass mirrors for selective wavelength separation. Constructed on fused silica substrates with highly polished front and back surfaces, they maintain excellent thermal and dimensional stability.
DLHS mirrors offer over 99% reflection at 266 nm, providing optical precision, durability, and long-term stability. They are well-suited for advanced laser systems, scientific research, and demanding industrial applications.
