Dielectric-Coated Plane Mirrors DLB SBB 350-950 nm
LINOS® DLB SBB 350–950 nm Dielectric-Coated Plane Mirrors are extremely broadband, highly reflective mirrors designed for versatile high-performance laser applications. Their advanced dielectric coating ensures excellent reflectivity across a wide spectral range, providing reliable performance for precision optical systems. Optimized for beam steering at a 45° angle of incidence, they deliver accurate 90° beam deflection while maintaining extremely low scattering losses. The polished back surface on the fused silica substrate enhances mechanical stability and handling, minimizing stress and the risk of damage during installation.
Constructed on high-quality fused silica, these mirrors offer outstanding thermal and mechanical stability, making them ideal for demanding applications in research, laboratory, and industrial environments. Their combination of broadband reflection, low-loss performance, and precise beam control ensures consistent and reliable operation across a wide range of wavelengths.
