  • MgF2 AND LIF AND RARE-EARTH FLUORIDE FILMS FOR ALUMINUM MIRRORS FOR FAR-ULTRAVIOLET SPECTRAL REGION AND METHOD OF MAKING SAME
    Publication number: 20170031067
    Abstract: The present invention relates to enhanced magnesium fluoride (MgF2) and lithium fluoride (LiF) over-coated aluminum (Al) mirrors, for far-ultraviolet (FUV) spectral region, and a method of making same. In addition, the present invention relates to rare-earth fluorides such as gadolinium fluoride (GdF2) and lutetium fluoride (LuF3) films, which are used as high-index layers, that when paired with the lower index MgF2, will provide multilayer coatings operable in the FUV spectral region.

  • Method for milling and drilling glass
    Patent number: 4383785
    Abstract: A process for machining glass by placing a rotating carbide working surface under minimum pressure against an area of glass to be worked and concurrently wetting the region between the working surface and the area of glass with a lubricant consisting essentially of a petroleum carrier, a complex mixture of esters and a complex mixture of naturally occurring aromatic oils.

  • Method of forming a sharp edge on an optical device
    Patent number: 4198788
    Abstract: A method of forming a sharp edge on an optical device. The method involves the steps of placing the optical device in a holding mechanism; grinding one surface of the optical device so the one surface and a surface of the holding mechanism are co-planer; and polishing the one surface of the optical device and the surface of the holding mechanism with felt until an edge on the one surface of the optical device adjacent the surface of the holding mechanism obtains a desired sharpness.

  • Method of treating the surface of a glass member
    Patent number: 4046619
    Abstract: A method of treating a surface of a glass member intended to abut a transparent element for disrupting the light interference fringes formed therebetween. The method involves the steps of grinding the surface to form irregularities thereon; bathing the surface with an aqueous solution containing between substantially 41.3 percent and 45.7 percent by volume of sulfuric acid and between substantially 54.3 percent and 58.7 percent by volume of hydrofluoric acid for a time sufficient to polish the irregularities until the glass member is about 90 percent light transmissive; and washing the glass member with a liquid having a temperature substantially lower than the temperature of the aqueous solution for preventing further reaction between the aqueous solution and the surface.
