BARIUM FLUORIDE (BaF2) LENSES

Alkor Technologies - manufacturer of custom Barum Fluoride lenses. Barium Fluoride lenses can be used in the ultraviolet, visible and infrared spectral regions. Barium Fluoride has transmission above 90% between 0.25 and 9.5µm. We can make lenses from 3 to 80mm diameter with almost any focal length.

We produce custom:

  • plano-convex BaF2 lenses;
  • planoconcave BaF2 lenses;
  • biconvex BaF2 lenses.

    • E-mail us for quote.

    We have own growth facility for BaF2 crystal growth. That is why we offer Barium Fluoride BaF2 lenses at very competitive price - up to 80% lower than major online optical catalogs!

    FAQ: ordering information, delivery and payment terms.

    Barium Fluoride is used for lenses, particulary when transmission into the ultraviolet is desired. The transmission range of BaF2 is from 0.2 to 11µm. Transmission in the VUV is degraded by prolonged exposure to moist atmospher, but it is not significantly degraded by exposure to high energy radiation.
