Undoped YAG is a substrate material that can be used for UV and IR optics. Sapphire has been the substrate of choice for these applications; however it is difficult to polish Sapphire to a 10-5 scratch-dig finish,and is also slightly birefringent. YAG is non-birefringent and can be polished to a 10-5 scratch surface quality.
