The CAW15 is a 50.0 mm in diameter and 3.0 mm thick Calcium Fluoride window. Calcium fluoride has a wide spectral range with high transmission (above 90%) between 0.25 μm and 7 μm, making it an excellent choice for deep UV to IR applications. CaF2 is also an ideal choice for excimer laser optics due to its low absorption and high damage threshold. For selected applications CaF2 can also be used without an anti-reflective coating as it has a low index of refraction leading to a low refracted light from the second surface.

CAW15直径为50.0 mm，厚度为3.0 mm的氟化钙窗。氟化钙具有宽光谱范围传输高(90%以上)0.25μm和7μm之间,使其深紫外红外应用程序的一个很好的选择。CaF2由于低吸收和高损伤阈值，也是准分子激光光学的理想选择。对于选定的应用，CaF2也可以不使用抗反射涂层，因为它具有低折射率，导致第二表面的低折射光。
