Low Delayed Barium Fluoride

Low delayed barium fluoride crystals have a transmittance of 90% in the spectral range of 200-9500nm. Used in lenses, beam splitters, filters, prisms, and window sheets in low-temperature refrigeration imaging, aerospace optics, and laser optical systems. It has a certain degree of water solubility and is suitable for use in dry environments. The phase delay caused by the deviation of the phase of light when passing through substances with biphasic or multidirectional properties is called phase delay; Barium fluoride material belongs to the tetragonal crystal system and is isotropic, with slight differences in different directions. To obtain accurate monitoring signals, low phase delay is required. Machinable shapes include circular, rectangular, perforated, crescent, wedge-shaped, flat convex, flat concave, double convex, double concave, open ball, and prismatic.
