Calcium Fluoride (CaF₂) Plano-Convex (PCX) lenses
Calcium Fluoride (CaF₂) Plano-Convex (PCX) lenses are high-quality optical components..

Also, they are widely used in precision laser systems, spectroscopy instruments, and infrared imaging.

Known for their broadband transmission, low dispersion, and excellent optical clarity, CaF₂ PCX lenses provide superior performance across ultraviolet (UV), visible, and infrared (IR) wavelengths.

Applications:

 

  • Laser Systems
  • Spectroscopy Instruments
  • Infrared Imaging
  • Lithography & Optical Inspection

Why Choose Calcium Fluoride (CaF₂) Lenses?

Calcium Fluoride is a preferred optical material due to its unique combination of optical and physical properties:

  • Broad Wavelength Transmission: Transmits light from 0.13 µm (UV) to 9 µm (IR), making it ideal for multi-spectral applications.
  • Low Refractive Index and Dispersion: Reduces chromatic aberrations, ensuring sharp and precise focusing.
  • High Laser Damage Threshold: Also, it is suitable for high-power laser systems.
  • Thermal Stability: Low thermal expansion minimizes distortion under varying temperatures.

 

 

Also, the calcium fluoride plano-convex lenses are highly suitable for applications requiring excellent performance across the ultraviolet to mid-infrared spectral range.

These lenses feature low refractive index, high laser damage threshold, and low axial and radial stress birefringence, making them ideal for use with excimer lasers or integration into infrared systems.

FAQS

1.  What is a Calcium Fluoride (CaF₂) Plano-Convex Lens?

A CaF₂ PCX lens is an optical lens with one flat (plano) surface and one convex surface, made from calcium fluoride.

2. Can CaF₂ lenses be coated?

Yes, AR coatings can be applied to improve transmission and reduce reflections, especially for specific wavelength ranges in UV, visible, or IR. You can dicide according to the using environments.

3. Are CaF₂ PCX lenses available in custom sizes?

Yes, Chenyu offers custom diameters (from a few millimeters up to several inches) and focal lengths.
