Dielectric-Coated Plane Mirrors DLHS NIR 1064 nm
LINOS® DLHS NIR 1064 nm Dielectric-Coated Plane Mirrors are designed for high-power and high-energy laser applications. They deliver exceptional reliability and optical performance. Their advanced dielectric NIR coating resists laser-induced damage and ensures reflection above 99.8%. These mirrors are made for a 45° angle of incidence and provide precise 90° beam deflection. They also serve as short-pass or dichroic elements in complex optical setups.
The fused silica substrate offers excellent thermal and mechanical stability. The super-polished front surface, with an RMS roughness of ≤ 1 nm, minimizes scatter and maintains beam quality. These mirrors deliver very low scattering losses, making them ideal for precision beam steering in high-performance laser systems.
