Abstract: A method for producing an optical apparatus includes providing a pair of glass wafers. One or more diffractive optical elements (DOEs) are formed on one or more of the glass wafers. A spacer is positioned between the glass wafers so as to define a cavity containing the DOEs, and a hermetic seal that bonds the glass wafers together and seals the cavity is formed.

Abstract: An optical device includes a first plate having a first transparent region defining an exit face of the device, and a second plate having a second transparent region defining an entrance face of the device. At least one lens is formed over at least one of the first and second transparent regions. First and second planar reflectors are spaced apart and fixed between the first and second plates in mutually-parallel orientations diagonal to the first and second plates, thereby defining an optical path through the device from the entrance face, reflecting from the first and second reflectors, through the exit face and passing through the at least one refractive surface.

Abstract: This application relates to manufacturing techniques for producing thin magnetic elements. In particular, the manufacturing processes are designed to accommodate the mechanical properties of sintered magnetic substrates. One of the manufacturing processes involves cutting a magnetizable substrate into a number of slices and adhesively coupling the slices to a sheet that can take the form of a layer of grinding tape. After concurrently grinding a first surface of each of the slices, the slices are flipped over so that the first surface of each slice is attached to another layer of grinding tape. A second surface of each of the slices is then ground until a desired thickness is achieved. Subsequent to the grinding, dicing operations can be applied to the slices to produce magnets having a desired length and width.
