ISP Optics Barium Fluoride (BaF2) Plano-Convex (PCX) Lenses are ideal for collecting and focusing light in ultraviolet, visible, and infrared applications. Barium Fluoride has similar physical properties to Calcium Fluoride, but provides a higher resistance to high-energy radiation. However, it is less resistant to water and prolonged exposure to moisture can degrade transmission in the ultraviolet range. ISP Optics Barium Fluoride (BaF2) Plano-Convex (PCX) Lenses feature a low index of refraction that enables excellent transmission from 0.2- 12μm without the need for Anti-Reflection (AR) coatings. These lenses are available in standard imperial sizes with focal length options from 25 – 500mm.
Note: These lenses are very sensitive to thermal shock.
