Extra charges may applies. Thorlabs also offers dielectric concave mirrors that provide higher reflectivity than metal mirrors at the expense of operating over a more narrow wavelength range. We are already in contact with you about this quote. In the following table you may find typical lead times. Do not rub the surface with paper or cloth as this will harm the surface. The AL.2 UV enhanced aluminum coating is a durable, broadband UV reflector with an average reflectivity greater than 90% from 250-600 nm. Metallic-coated mirrors offer relatively high reflectivity (90-95%) over a wide wavelength range, while dielectric-coated mirrors provide even higher reflectivity (>99%) but over a smaller wavelength range.
