Calcium Fluoride Plano-Convex (PCX) Lenses

  • Greater than 90% Transmission from 200nm - 7μm
  • Low Index of Refraction
  • Vacuum Grade UV Substrate

TECHSPEC® Calcium Fluoride Plano-Convex Lenses are ideal for demanding applications that require superior performance from the ultraviolet through the mid-wave infrared spectra. TECHSPEC Calcium Fluoride PCX Lenses’ low refractive index, high laser damage threshold, and low axial and radial-stress birefringence are highly suitable for use with Excimer lasers or for integration into infrared systems. Additionally, calcium fluoride features low solubility and offers superior hardness to comparable fluoride-based substrates, making these PCX lenses capable of withstanding harsh environments and exposure to the elements.
