Introduction

Used as transparent barriers for sending and receiving light between two phases under varying conditions in temperature pressure chemical composition cleanliness and phase. Fused Silica windows are used for visible and near IR. AR coated Fused Silica windows allowed more than 99％ transmittance comparing with 92％ of uncoated one.
