Description
Optical Grade High-Purity Fluorspar, CaF₂ ≥ 99% (4N) | Ultra-Low Impurity for Precision Optics

Product Introduction

This is 4N high-purity optical grade fluorspar with CaF₂ content stably above 99%. It is a core base material for manufacturing high-end optical lenses, IR/UV optical windows, prisms and special optical instruments. Produced via multi-stage purification and precision crystallization, with arsenic (As) strictly controlled at ≤0.01%, the material features extremely low impurities and excellent crystal uniformity. It offers high transmittance across a wide spectrum, ultra-low dispersion and stable refractive index, effectively reducing chromatic aberration and distortion in optical systems while improving imaging clarity and performance. It meets the strict manufacturing requirements of high-end fields such as scientific research, medical care, industrial inspection and aerospace, supporting customized specifications and long-term bulk export orders.

Core Advantages

  1. Extreme purity control for consistent optical performance
    4N ultra-high purity (CaF₂ ≥ 99%) combined with low arsenic content (≤0.01%) eliminates impurity interference with optical transmittance and refractive index uniformity at the source. It ensures highly stable optical performance across batches, reducing the defect rate of optical components and meeting precision tolerance requirements for high-end optical manufacturing.
  2. Superior optical properties for diverse high-end applications
    With excellent UV-IR dual-band transmittance, ultra-low dispersion and high radiation resistance, it is suitable for manufacturing various optical components from UV to IR bands. It adapts to complex working conditions in scientific instruments, medical equipment, industrial inspection, aerospace and other fields, providing reliable performance support for high-end optical systems.

FAQ

Q1: What is the essential difference between optical grade fluorspar and other grades?
A: Optical grade fluorspar requires ultra-high purity (≥99%), 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 core value of 4N (≥99%) high purity for optical products?
A: High purity reduces light scattering and absorption caused by impurities, improving the transmittance of optical components. 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.
