FAQ

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

A: Optical grade fluorspar focuses on ultra-high purity, extremely low impurities and uniform crystal structure to ensure key optical properties such as transmittance and refractive index uniformity. Acid grade, metallurgical grade and building grade fluorspar have much lower purity and impurity control standards and cannot meet the precision requirements of optical manufacturing; they are not interchangeable.

Q2: What is the key value of 4N (≥99%) high purity for optical products?

A: High purity is the foundation of optical performance, reducing light scattering and absorption caused by impurities and improving transmittance. It also reduces refractive index fluctuations, minimizing optical defects such as chromatic aberration and distortion, significantly enhancing imaging clarity and optical system stability, which is essential for high-end optical components.

Q3: What practical significance does low arsenic content have for optical grade fluorspar?

A: Impurities such as arsenic can disrupt crystal structure uniformity, leading to uneven local optical performance and potential performance degradation under high-energy radiation or high temperatures. With As ≤0.01%, our product effectively avoids these issues, ensuring long-term stability and reliability of optical components under complex conditions.

Q4: Can specifications be customized according to optical design requirements?

A: Yes. We can provide customized products with different shapes, sizes or purity levels based on your optical design, production process and equipment requirements to suit various optical component manufacturing needs.

Q5: How is stable long-term supply of optical grade fluorspar guaranteed?

A: We have a stable supply of high-purity ore and mature purification processes. Each batch undergoes strict optical performance and impurity testing. We support customized production and long-term export orders to ensure stable supply for overseas optical manufacturers.
