Product Family Description

  • Low Index of Refraction
  • IR Grade Calcium Fluoride Substrates
  • Standard Imperial Sizes for Easy Benchtop Integration

ISP Optics Calcium Fluoride (CaF2) Plano-Concave (PCV) Lenses feature IR grade calcium fluoride substrates, providing high transmission in the visible and infrared spectra. Calcium fluoride has a low index of refraction, enabling these lenses to be used without additional Anti-Reflection (AR) coatings. The PCV design diverges incident collimated beams, making them ideal for light projection and beam expansion applications. ISP Optics Calcium Fluoride (CaF2) Plano-Concave (PCV) Lenses are available in standard imperial sizes with focal lengths ranging from -25.4 to -500mm.
