MgF2 single crystal is a birefrigent material with particular properties. It has a high resistance to mechanical and thermal shock and radiation. With wide transparent range and high transmissibility, it becomes a popular choice for VUV and excimer laser windows, polarizers, prisms, lenses, wedges, windows, and other optical components
