Fluorite Lenses

Fluorite is a mineral that is used in a variety of applications, including optical lenses. It has a low dispersion, which means that it does not refract different colors of light at different angles. This makes it ideal for use in telescopes and camera lenses, as it helps to reduce chromatic aberration.

It’s used because its structure allows a window for both infrared and ultraviolet wavelengths to pass through thus creating a clearer sharper image.  Now, no more green fuzz found in your images -Fluorite makes it disappear. 

Fluorite has several properties that make it ideal for use in lenses

• Low dispersion: Fluorite has a very low dispersion, which means that it does not refract different colors of light at different angles. This helps to reduce chromatic aberration, which is a type of lens distortion that causes objects to appear blurry or out of focus.
• High transmission: Fluorite is a very transparent material, which means that it allows a lot of light to pass through it. This results in images that are bright and clear.
• High refractive index: Fluorite has a high refractive index, which means that it bends light more than other materials. This can be used to create lenses that are more compact and lightweight.

Natural fluorite is often too flawed for optical use, so synthetic fluorite is often used instead. Synthetic fluorite can be grown in controlled conditions, which ensures that it is free of flaws and impurities.

Canon Inc. is one of the companies that uses synthetic fluorite in their telephoto lenses. Their fluorite lenses are known for their high image quality and low chromatic aberration.

Fluorite has a very low dispersion, so lenses made from it exhibit less chromatic aberration than those made of ordinary glass.

Advantages of fluorite lenses

• Superior image quality: Fluorite lenses produce sharper, higher-contrast images with less chromatic aberration than traditional glass lenses.
• Wider spectral range: Fluorite lenses transmit light well across a wider range of wavelengths, making them suitable for use in ultraviolet and infrared photography.
• Lighter weight: Fluorite is lighter than glass, which can be an advantage for large lenses.

Overall, fluorite is a valuable material for use in telescopes and camera lenses. It offers a number of benefits over other materials, including low dispersion, high transmission, high refractive index, and durability.
