Product Description

Detailed Specifications & Features

4N Optical Grade Fluorspar | CaF₂ ≥ 99% for Precision Optics

Product Introduction

Our high-purity optical grade fluorspar has CaF₂ content ≥ 99% (4N). It is a core raw material for manufacturing high-end optical lenses, prisms and optical instruments. With extremely low impurity levels, it features excellent light transmittance, low dispersion and thermal stability, effectively eliminating chromatic aberration and improving imaging clarity.

Core Advantages

Ultra-High 4N Purity, Superior Optical Performance

CaF₂ ≥ 99% with minimal impurities ensures excellent UV/IR transmittance and extremely low dispersion. It eliminates chromatic aberration and enhances imaging clarity, ideal for premium optical components.
Excellent Thermal Stability & Reliability

The high-purity crystal structure provides outstanding thermal shock resistance. Optical performance remains stable under temperature variations, suitable for precision optical instruments and industrial lenses.
Strict Impurity Control, Consistent Quality

Harmful impurities are strictly limited to avoid light scattering and imaging defects. Every batch maintains consistent optical performance to meet the strict requirements of precision optics manufacturing.

Q&A

Q1: What is the main function of optical grade fluorspar?

A: It is used as raw material for lenses and prisms. Its low dispersion eliminates chromatic aberration and improves imaging clarity, while high transmittance boosts light transmission efficiency.

Q2: Why is 4N purity important?

A: ≥99% purity minimizes light scattering and absorption, ensuring optical uniformity, excellent transmittance and low dispersion to meet high-end optical equipment requirements.

Q3: How does impurity control affect optical quality?

A: Impurities cause reduced transmittance, light scattering and imaging defects. Strict control ensures stable performance and avoids material-related optical issues.

Q4: How to choose between crystal and powder forms?

A: Crystals are suitable for direct processing into lenses and prisms; powder is used for special optical glass or crystal growth. Custom sizes are available upon request.

Q5: What about delivery and packaging?

A: We provide stable supply with professional packaging to prevent damage during transit, tailored to meet the production needs of precision optics manufacturers.
