Chenyu Calcium fluoride double-convex lenses
Calcium Fluoride Double-Convex (DCX) lenses are highly suitable for limited imaging applications that require high transmittance in the infrared wavelength spectrum.

Calcium Fluoride Double-Convex (DCX) lenses are widely used in precision optical systems.

With their excellent transmission range, low refractive index, and outstanding resistance to laser damage.

A double convex lens will focus light onto a single point. These lenses are made up of two convex surfaces of equal radius.

Therefore, they are ideal for applications requiring high performance in the ultraviolet (UV), visible, and infrared (IR) spectral regions.

Calcium Fluoride Double-Convex (DCX) Lenses

The properties of CaF2

  • Calcium Fluoride (CaF₂) offers superior transmission in the UV and IR.
  • Lower dispersion than typical crown glasses, enabling clearer and sharper imaging.
  • Better resistance to environmental degradation compared to many fluoride crystals.

Applications of Calcium Fluoride Double-Convex Lenses

  • UV and IR Imaging Systems: Suitable for telescopes, microscopes, and cameras.
  • Laser Optics: In excimer lasers, femtosecond lasers, and high-power IR laser systems.
  • Spectroscopy: Suitable for analytical instruments.
  • Astronomy & Aerospace: Preferred in space-borne instruments for their radiation resistance and optical clarity.
  • Medical and Scientific Instruments: From lithography to biomedical imaging.
