MSE PRO™ BK7 Protected Silver Mirrors
MSE supplies offers BK7 Protected Silver Mirrors. Protected silver coating offers a higher surface reflectivity than the enhanced aluminum coating. It provides an average reflection of approximately 95% in the visible wavelength range. This coating is a hybrid shelf life. The silver layer is protected both underneath and above with dielectric layers which minimizes tarnishing and allows cleaning by normal laboratory methods. These mirrors have very high reflectivity from 0.45m through to the infrared spectrum.
MSE Supplies can offer a variety of optical elements, with different focal length and coating options. Please contact us for customization or bulk orders.
