12.7mm Dia. 320 – 450nm Broadband λ/10 Mirror

Product Details Enhanced Reflectivity and LIDT over Metallic Coatings Average Reflectivity >99% Over Broad UV, Visible, and NIR Wavelengths Designed for all Polarization States from 0 – 45° AOI TECHSPEC Broadband Dielectric λ/10 Mirrors are ideal for beam steering or reflection applications utilizing multiple laser sources. These mirrors feature greater than 99% reflection, significantly better than metal-coated mirrors, and increase system performance by minimizing energy loss. The highly durable fused silica substrate offers a low thermal expansion coefficient and a high abrasion resistance. TECHSPEC Broadband Dielectric λ/10 Mirrors are designed for applications from the UV to the near-infrared spectra.
