20090141358	DENSE HOMOGENEOUS FLUORIDE FILMS FOR DUV ELEMENTS AND METHOD OF PREPARING SAME - The invention is directed to optical elements that are coated with dense homogeneous fluoride films and to a method of making such coated elements. The coatings materials are a high (“H”) refractive index fluoride material and a low (“L”) refractive index material that are co-evaporated to form a coating layer of a L-H coating material (a co-deposited coating of L and H materials). Lanthanide metal fluorides (for example, neodymium, lanthanum, dysprosium, yttrium and gadolinium, and combinations thereof) are preferred metal fluorides for use as the high refractive index materials with lanthanum fluoride (LaF	06-04-2009
20090297812	Adhesive, hermetic oxide films for metal fluoride optics and method of making same - The invention is directed to single crystal alkaline earth metal fluoride optical elements having an adhesive, hermetic coating thereon, the coating being chemically bonded to the surface of the metal fluoride optical element with a bonding energy ≧4 eV and not merely bonded by van de Walls forces. The materials that can be used for coating the optical elements are selected from the group consisting of SiO	12-03-2009
