The MGW13 is a 50.0 mm in diameter and 3.0 mm thick Magnesium Fluoride window. Magnesium fluoride has a wide spectral range with high transmission between 0.15 μm and 6.5 μm, making it an excellent choice for deep UV to IR applications. MgF2 has high resistance to thermal and mechanical shock, as well as laser damage. For selected applications MgF2 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.

MGW13直径为50.0毫米，厚度为3.0毫米的氟化镁窗。氟化镁与高宽光谱范围0.15μm和6.5μm之间的传播,使其深紫外红外应用程序的一个很好的选择。MgF2具有较高的抗热、机械冲击和激光损伤能力。对于选定的应用，MgF2也可以不使用抗反射涂层，因为它具有低折射率，导致来自第二表面的低折射率光。
