Barium Fluoride (BaF2) Windows
Broad Transmission Range: High transmission from 0.2 µm to 11.0 µm, suitable for both UV and IR applications.
Low Refractive Index: ~1.48, ensuring high transmission rates without the need for anti-reflection coatings.
Radiation Resistance: More resistant to high-energy radiation compared to CaF2, making it suitable for harsh environments.
Thermal Stability: Can endure temperatures up to 800 °C when dry, although sensitive to moisture at higher temperatures.
Extended LWIR Transmission: Transmission range stretches about 1 micron further into the LWIR spectrum compared to CaF2.
Applications: IR spectroscopy, thermal imaging, UV applications, high-energy radiation environments, etc.
