  • Patent number: 10049848
    Abstract: Technologies are described for methods for fabricating a film component. The methods may comprise sputtering a first film onto a substrate. The first film may include a semiconductor compound material. The semiconductor compound material may include a semi-metal material and one or more alkali material. The methods may further comprise evaporating a second film onto the first film. The second film may include the one or more alkali materials. The one or more alkali materials may catalyze crystallization of the semiconductor compound material in the first film substantially throughout the first film to form the film component in the first layer.

  • Patent number: 8130902
    Abstract: Active optics apparatus and method for aligning active optics are provided for a high-resolution, active optic fluorescence analyzer combining a large acceptance solid angle with wide energy tunability. A plurality of rows of correctors selectively controlled to bend an elongated strip of single crystal material like Si (400) into substantially any precisely defined shape. A pair of pushers engages opposite ends of the silicon crystal strip exert only a force along the long axis of the crystal strip, and does not induce additional bending moments which would result in a torsion of the crystal.
