FAQ

Q1: What is the main difference between optical grade fluorspar and other grades?

A: Optical grade fluorspar requires ultra-high purity above 99% and extremely strict impurity control to guarantee optical performance. Metallurgical, ceramic and building grade fluorspar have lower purity standards and cannot be used for optical production.

Q2: Why is 4N high purity essential for optical products?

A: High purity reduces light absorption and scattering caused by impurities, and stabilizes the refractive index. It greatly lowers optical defects such as chromatic aberration, and ensures clear imaging and stable operation of optical devices.

Q3: What is the function of low arsenic content for optical fluorspar?

A: Excessive arsenic will damage crystal uniformity and affect optical stability. Our product with low arsenic content keeps crystal structure intact, ensuring reliable performance of optical components under high temperature and radiation conditions.

Q4: Can you provide customized products?

A: Yes. We can customize product shape, size and related specifications according to your optical design and production techniques.

Q5: Can you ensure stable long-term supply?

A: We have reliable high-purity ore sources and mature purification techniques. Every batch undergoes strict optical and impurity testing. We provide steady supply and professional service for overseas optical manufacturers.
