About Hellma Materials
Calcium fluoride is, due to its unique features, the ideal basic material for several sectors. Based on its high radiation resistance and optical quality when hit by laser, calcium fluoride is used e.g. as a lens material in lithography. Not only astronomy, photography and microscopy but also HDTV optics and medical laser instruments can benefit from the innovative high-tech material. Our excellent know-how in producing calcium fluoride allows the fabrication of blanks in diameters up to 350nm and with thicknesses up to 100mm.
