Product Description

Detailed Specifications & Features

4N High-Purity Optical Grade Fluorspar (CaF₂ ≥ 99%) | Low-Arsenic for UV & IR Optics

Product Introduction

This is 4N high-purity optical grade fluorspar with CaF₂ content stably above 99%. It is a core raw material for UV-IR broadband optical systems, special optical lenses, high-temperature optical windows and precision prisms. Produced from carefully selected high-purity fluorspar ore through wet purification, directional crystallization, high-temperature impurity removal and other rigorous processes, with arsenic (As) strictly controlled at ≤0.01%, it features minimal crystal defects and excellent uniformity. It offers outstanding broadband transmittance, ultra-low dispersion and high radiation resistance, effectively eliminating chromatic aberration and improving imaging resolution. It meets the optical manufacturing standards of high-end fields such as scientific research, medical care and aerospace, supporting customized specifications and long-term bulk export orders.

Core Advantages

4N extreme purification for zero optical performance interference

With CaF₂ purity ≥ 99% and As ≤ 0.01%, impurity control meets the highest optical grade standards. It eliminates impurity interference with light scattering, absorption and refraction at the source, ensuring high transmittance, low dispersion and refractive index uniformity across the UV to IR spectrum, meeting precision tolerance and batch consistency requirements of high-end optical systems.
Broadband compatibility for diverse high-end applications

Combining excellent UV transmittance, IR transmittance and ultra-low dispersion, as well as good thermal stability and radiation resistance, it is suitable for manufacturing various components from UV lenses and IR temperature measurement windows to aerospace optical payloads. It adapts to complex working conditions in scientific research, medical diagnosis, industrial inspection and aerospace, providing stable and reliable performance support for high-end optical systems.

FAQ

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

A: Optical grade fluorspar focuses on 4N ultra-high purity, extremely low crystal defects and uniform optical performance with As ≤0.01% to ensure broadband transmittance and low dispersion. Acid grade, metallurgical grade and building grade fluorspar have much lower purity and impurity control standards and cannot meet the strict requirements of optical manufacturing; they are not interchangeable.

Q2: What is the core 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.
