Remarkable 
  • Strontium fluoride offers a wide range of transparency from the ultraviolet to the long wave infrared with low reflection loss and low dispersion
  • It´s thermo-optic coefficient is negative, which can compensate for the thermal lens effect in laser applications
  • Maximum available diameter is 190 mm
