Lead difluoride, PbF2

Lead difluoride (PbF2) is a crystalline compound that exhibits notable optical properties. It has a wide transmission range, spanning from the ultraviolet to the far-infrared region, making it an attractive choice for certain optical applications. In addition, PbF2 is used in the fabrication of specialty glass, especially in combination with heavy metals, to produce glasses with unique refractive properties. Its optical properties have also led to its consideration in infrared optics, such as in the production of lenses and windows for IR systems. However, due to the presence of lead, precautions should be taken when handling or working with PbF2 to minimize exposure.
