WebVery high reflectivity can be obtained between 0 and 45 degrees angle of incidence. These mirrors provide high reflectance with limited variation over a broad range of wavelengths. The dielectric multilayer coating makes the mirror surface highly resistant to scratches and allows for wiping for cleaning. Melting is effected at approximately 2200 °C (4000 °F) using either an electrically heated furnace (electrically fused) or a gas/oxygen-fuelled furnace (flame-fused). Fused silica can be made from almost any silicon-rich chemical precursor, usually using a continuous process which involves flame oxidation of volatile silicon compounds to silicon dioxide, and thermal fusion of the resulting dust (although alternative processes are used). This results in a transparent glass with an ultra-h…
