IR Windows Barium fluoride (BaF2) Windows


Barium fluoride (BaF2) shows good optical transmission over wide spectrum range, which can be used as UV-IR windows in 0.15μm~12.5μm. It also presents excellent scintillation properties, which is widely used in high energy physics, nuclear physics and nuclear medical instruments.

WTS make customized coated and uncoated BaF2 windows.


Note:When handling BaF2, please always wear gloves as it is a hazardous material.
