Re: Sapphire Right Angle Prisms

Sapphire prisms are precision optical components fabricated from high-purity single-crystal sapphire (Al₂O₃), engineered to redirect, disperse, or polarize light with exceptional durability and stability. Combining precise angular geometry with sapphire's outstanding material properties, these prisms deliver reliable optical performance in harsh environments where conventional glass prisms would degrade or fail.
