產品概覽

對200nm - 12μm範圍內的光具有極佳的穿透能力
對高能輻射有很好的抵抗能力
具備高穿透能力 (無抗反射鍍膜)

TECHSPEC®氟化鋇 (BaF₂) 窗口片對深紫外線至長波紅外線範圍的光具有很高的廣波段穿透能力，因此可用於多種應用 (例如紅外光譜儀)。氟化鋇的低折射率 (1.48) 可提供高穿透能力，而無需使用抗反射鍍膜。氟化鋇窗口片可在高達800°C的乾燥環境中使用，但若長時間置於潮濕環境內，會導致真空紫外線範圍內的穿透能力降級。氟化鋇窗口片的防水能力低於氟化鈣，是高能輻射抵抗能力最高的氟化光學元件，但紫外線穿透能力較低。BaF₂的努氏硬度為82。

注意：這些光學窗口片對熱衝擊非常敏感。

Barium fluoride is a fast scintillator and can be used to detect X-rays, gamma rays, or other high energy particles such as 511 keV gamma photons in Positron Emission Tomography (PET). BaF₂ can also be used to detect high-energy neutrons and separate them from simultaneously occurring gamma photons using pulse shape discrimination techniques.
