Magnesium Fluoride Crystal Description

Magnesium Fluoride Crystal is an inorganic compound with the chemical formula MgF2. It is a white crystalline solid that is highly transparent to ultraviolet, visible, and infrared light.

It is widely utilized across various fields due to their excellent optical and physical properties. They find applications in optical coatings, windows, lenses, and modulators. Beyond optics, MgF₂ also serves as a metallurgical additive for deoxidation. Stanford Optics is a trusted manufacturer and supplier dedicated to providing premium-quality magnesium fluoride crystals tailored for diverse industrial and scientific needs.

Magnesium Fluoride Crystal Application

  1. Optical Coatings
    Magnesium fluoride is widely used as an anti-reflective coating on lenses, windows, and mirrors. Its ability to reduce surface reflections and enhance light transmission makes it essential for cameras, telescopes, microscopes, and other optical instruments.

  2. Ultraviolet (UV) Optics
    Thanks to its broad transmission range extending into the deep ultraviolet region, magnesium fluoride is commonly employed in UV optics applications such as lithography, fluorescence spectroscopy, and UV imaging.

  3. Excimer Lasers
    This material is a key component in excimer lasers, providing a high laser-induced damage threshold and low optical absorption, which are crucial for the performance and durability of high-energy pulsed gas lasers used in medical, industrial, and scientific fields.

Magnesium Fluoride Crystal Advantages

Exceptional Optical Quality: High transmission rates and minimal absorption enable sharp, precise imaging across a broad spectral range.

Robust Durability: Resistance to environmental degradation and chemical corrosion ensures longevity and reduces maintenance frequency.

Wide Spectral Compatibility: Suitable for applications spanning from ultraviolet to infrared wavelengths, enhancing versatility.

FAQ
Q1: What are the main applications of magnesium fluoride crystals?

Magnesium fluoride crystals are mainly used in optical components such as UV and infrared windows, lenses, and prisms. They are also important in laser systems for beam steering and focusing, telescope optics in astronomy, and spectroscopy systems covering both infrared and ultraviolet wavelengths.

Q2: What surface finish options are available for magnesium fluoride crystals?

The crystals can be polished to achieve very smooth surfaces with roughness (Ra) below 5 Å for high-precision optical applications. Ground surfaces are also available for experimental or industrial uses, and custom roughness levels can be provided to meet specific requirements.

 

Q3: What types of coatings can be applied to magnesium fluoride crystals?

Common coatings include anti-reflective coatings optimized for specific wavelengths to improve optical performance, protective coatings designed for harsh environmental conditions, and custom multi-layer coatings suitable for broad or multi-wavelength applications.
