Materion Thorium Fluoride, ThF4
Categories:	Other Engineering Material
Material Notes:	Thorium Fluoride, ThF4 provides the lowest absorption at 10.6µm wavelength and has been the mainstay for high energy applications where high damage thresholds are required. Because Thorium Fluoride is a naturally radioactive material and special handling and disposal procedures must be followed, continuing searches are underway for alternate, non-radioactive substitutes.
