Fiber Shield windows are designed to shield optical components in laser beam delivery systems from debris, fumes, and other pollutants. The fused-silica windows have clear apertures for maximum absorption and reflection, and a coating to protect against dross, oils, and particulates. They are available in diameters from 0.47 to 2.17 in.
