12.7mm Dia. UHR Broadband Dielectric Mirror, 400-750nm

Product Details >99.8% Reflectivity over Broad Visible or NIR Wavelength Ranges 10-5 Surface Quality for Reduced Scatter in Sensitive Laser Applications λ/10 Surface Flatness Ultra-High Reflectivity (UHR) Broadband Dielectric Mirrors are ideal for use with broadband laser or illumination sources in applications that require low reflection loss. These mirrors feature laser grade substrates with λ/10 surface flatness and 10-5 surface quality to minimize scattering effects. Coated with durable dielectric coatings, these mirrors are designed for >99.8% average reflectivity throughout the visible (400 – 750nm) or NIR (740 – 1100nm) spectra, independent of polarization. With a high-quality fused silica substrate, Ultra-High Reflectivity (UHR) Broadband Dielectric Mirrors feature a low coefficient of thermal expansion. Coating Note: Coating designs measured and verified at 532, 632.8, and 1064nm via cavity ring-down spectroscopy (CRDS). Specs may not be verifiable on traditional spectrophotometer equipment.
