4N High Purity Optical Grade Fluorspar, CaF₂ ≥ 99% | For Precision Optical Components
Product Introduction
This is high-purity optical grade fluorspar with 4N purity and calcium fluoride content above 99%. It serves as a core raw material for manufacturing high-end optical glass, lenses, prisms, optical windows and other precision optical parts. Produced via multi-stage purification and sophisticated processing, the material features extremely low impurity content and uniform crystal structure. It delivers outstanding transmittance across ultraviolet and infrared spectrum, steady refractive index and excellent radiation resistance. It effectively improves imaging definition, light transmittance and service life of optical products, fully complying with strict standards of high-end optical manufacturing. We accept customized specifications and support bulk export orders.
With CaF₂ content over 99% and arsenic content controlled below 0.01%, this product minimizes interference from impurities. It maintains high light transmittance and low light scattering in a wide spectral range, reducing chromatic aberration and distortion to meet high-precision requirements of advanced optical systems.
Superior comprehensive properties for diverse high-end applications
It boasts low dispersion, excellent UV and IR transmittance, as well as strong radiation resistance. It is widely applicable to UV lenses, infrared optical windows, high-temperature optical parts and precision instruments, covering aerospace, medical treatment, industrial inspection and scientific research fields.

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.
