Fused Silica Wafer is made from alumina silicate glass and borosilicate glass. It is an ideal material for many applications due to its excellent optical properties and low coefficient of thermal expansion. It has a wide range of uses including optical components, semiconductor wafers and microelectronic components. Fused Silica Wafer is available in different sizes, ranging from 2 to 12 inch in diameter. It has a bevel of 0.25mm X 45° and has a warp of less than 35um. It has a low TTV of less than 2um and less than 5um. Moreover, it can be coated with AR, HR, and V-Coat for various purposes.
