Product Description
Product Overview
Lithium Tantalate (LiTaO3) polishing wafers feature exceptional optical properties with a wide transparency range from ultraviolet to infrared (0.275-5.25 µm). These wafers undergo chemical mechanical polishing (CMP) to achieve ultra-smooth surfaces with Ra roughness values as low as 1.7Å, making them ideal for high-precision optical applications.
