Surplus Optics provides Barium Fluoride (BaF2) lenses which are ideal for applications such as infrared spectroscopy, laser systems, and thermography, due to its high transmission throughout UV, visible, and up to mid-wave infrared (MWIR) wavelengths.  

Barium Fluoride offers considerable advantageous capabilities including:
•    Excellent transmission above 90% between 0.2-10µm.
•    High-energy radiation resistance, ideal for VUV applications.
•    Low dispersion 
•    Ability to work in dry environments up to 800°C

Consideration should be taken as barium fluoride’s capabilities, especially its UV transmission, rapidly degrade when exposed to moisture.

Surplus Optics can also offer coated BaF2 lenses, subject to availability.
