The absorption in the vacuum and near ultraviolet region of CaF2 crystals containing lead and oxygen has been measured. Two main absorption bands at 155 and 202 nm are presumably due to lead centres and the band at 206 nm to oxygen. The nature of the weak band at 166 nm remains obscure. The absorption below 145 nm is probably due to excitons.
