氟化钡能很好应用于光谱组件。 氟化钡通常适用于无源IR波段(8~14μm)的应用,通常用作热成像的窗片。 对于相同厚度,比氟化钙的透射范围进一步延伸到IR中大约1mm。 主要用于IR应用,并注意到具有IR抛光的视窗可能在由低纯度BaF 2晶体制成的VUV中具有受限的透射性能。
氟化钡通过真空Stockbarger技术生长。 与CaF2不同,BaF2不以天然状态存在,并且所有材料必须化学合成,使得BaF2生产相对昂贵。氟化钡容易裂开,对热冲击非常敏感。它抛光好可以蚀刻。不是所有的晶体都是由zui高等级的化学品制造的; 对于IR级光学器件,较低规格是足够的并且降低了成本,然而在UV和VUV中的透射受到限制。zui高纯度的氟化钡VUV材料可以被认为是快闪烁级。
