Niobium pentoxide contributing to high refractive index control for optical glass.
Precise control of the refractive index of optical glass. Achieving both high transparency and high refractive index.
In the optical glass industry, precise control of the refractive index, which influences the performance of lenses and optical elements, is essential. Particularly in high-precision optical devices, the uniformity of light transmission and refractive index is crucial, as even slight contamination by impurities or particles can lead to performance degradation. Our Indian-sourced niobium pentoxide (Nb₂O₅) OPTICAL GRADE boasts a high purity of over 99.99%, making it an ideal material for controlling the refractive index of optical glass. It achieves both high transparency and high refractive index, contributing to the performance enhancement of cutting-edge optical devices, lenses, and electronic components. 【Application Scenarios】 - Optical lenses - Optical thin films - Prisms - Various optical elements 【Benefits of Implementation】 - Improved optical performance through high refractive index control - Enhanced light transmission due to high transparency - High quality through ppm-level impurity management - Establishment of a long-term stable supply system
