Sapphire wedge plate is a high-performance optical component known for its exceptional hardness, superior thermal stability, and precise beam deviation capabilities. Manufactured from crystalline sapphire (Al₂O₃), it offers outstanding optical clarity, excellent scratch resistance, and minimal optical distortion, making it ideal for laser systems, spectroscopy, aerospace applications, and precision scientific instruments. Its durability and ability to withstand extreme conditions ensure reliable performance in demanding optical environments.
Product Overview
The sapphire wedge plate is an optical component made from high-quality sapphire material, featuring a unique wedge-shaped design with two non-parallel surfaces, typically with an angle of 30 arcminutes. This design effectively eliminates interference effects (Etalon effect) caused by reflected light from highly parallel windows and reduces optical feedback in laser cavities, thereby improving laser output stability and preventing mode hopping. Sapphire wedge plates are commonly used in laser systems for beam sampling, light path adjustment, and laser output protection.
