High-purity niobium pentoxide contributing to refractive index control for optical glass.
Precise adjustment of the refractive index of optical glass. High-quality niobium pentoxide from Brazil.
In the optical glass industry, precise control of the refractive index, which influences the performance of optical elements such as lenses and prisms, is essential. Particularly in fields that require high-precision optical characteristics, the purity and composition of materials are crucial, as even slight impurities or variations in composition can significantly impact product performance. Our Brazilian niobium pentoxide (Nb₂O₅) is the optimal material for precisely controlling the refractive index of optical glass. With a purity of over 99.7% and stable quality, it contributes to solving challenges in the manufacturing process of optical glass. 【Application Scenarios】 - Lenses - Prisms - Optical Filters 【Benefits of Introduction】 - Precise control of refractive index - Improved optical characteristics - Higher product quality
