Dielectric-Coated Plane Mirrors DLHS UV 351-355 nm
LINOS® Dielectric-Coated Plane Mirrors DLHS UV 351–355 nm are precision optical components for high-power and high-energy laser applications. These mirrors feature a dielectric VUV high-power coating, providing high reflectance and very low scattering losses, ensuring reliable performance in demanding beam steering and deflection. Optimized for a 45° angle of incidence, they deliver precise 90° beam deflection and can also be used as dichroic or longpass mirrors for selective wavelength separation. The mirrors use fused silica substrates with highly polished front and back surfaces. This construction provides excellent thermal stability and minimal distortion.
With guaranteed reflection exceeding 99.5 % across 351–355 nm, DLHS mirrors combine optical precision, durability, and long-term reliability, making them ideal for advanced laser systems, scientific research, and high-power industrial applications.
