Westech produces plano work on double sided polishers. This insures flatness specs to 1/10 wave and lets us bring you this product at a cost effective price. Primary materials are N-BK7, Fused Silica and CaF2. Round and square windows are usually stocked in standard sizes. Westech can quickly make custom windows from any drawings or specifications or reduce the size of any in-stock windows to meet an immediate need. We offer stock and custom windows including Gorilla Glass.
