Abstract

This invention describes a method for fabricating an intraocular lens made rom clear Teflon.TM., Mylar.TM., or other thermoplastic material having a thickness of about 0.025 millimeters. These plastic materials are thermoformable and biocompatable with the human eye. The two shaped lenses are bonded together with a variety of procedures which may include thermosetting and solvent based adhesives, laser and impulse welding, and ultrasonic bonding. The fill tube, which is used to inject a refractive filling material is formed with the lens so as not to damage the lens shape. A hypodermic tube may be included inside the fill tube.

Zone compensated multilayer laue lens and apparatus and method of fabricating the same

Patent Conley, Raymond P.; Liu, Chian Qian; Macrander, Albert T.; ...

A multilayer Laue Lens includes a compensation layer formed in between a first multilayer section and a second multilayer section. Each of the first and second multilayer sections includes a plurality of alternating layers made of a pair of different materials. Also, the thickness of layers of the first multilayer section is monotonically increased so that a layer adjacent the substrate has a minimum thickness, and the thickness of layers of the second multilayer section is monotonically decreased so that a layer adjacent the compensation layer has a maximum thickness. In particular, the compensation layer of the multilayer Laue lensmore » « less

Fabrication process for a gradient index x-ray lens

Patent Bionta, Richard M [Livermore, CA]; Makowiecki, Daniel M [Livermore, CA]; Skulina, Kenneth M [Livermore, CA]

A process for fabricating high efficiency x-ray lenses that operate in the 0.5-4.0 keV region suitable for use in biological imaging, surface science, and x-ray lithography of integrated circuits. The gradient index x-ray optics fabrication process broadly involves co-sputtering multi-layers of film on a wire, followed by slicing and mounting on block, and then ion beam thinning to a thickness determined by periodic testing for efficiency. The process enables the fabrication of transmissive gradient index x-ray optics for the 0.5-4.0 keV energy range. This process allows the fabrication of optical elements for the next generation of imaging and x-ray lithographymore » instruments m the soft x-ray region. « less

Apparatus and method for non-contact, acoustic resonance determination of intraocular pressure

Patent Sinha, Dipen N [Los Alamos, NM]; Wray, William O [Los Alamos, NM]

Apparatus and method for measuring intraocular pressure changes in an eye under investigation by detection of vibrational resonances therein. An ultrasonic transducer operating at its resonant frequency is amplitude modulated and swept over a range of audio frequencies in which human eyes will resonate. The output therefrom is focused onto the eye under investigation, and the resonant vibrations of the eye observed using a fiber-optic reflection vibration sensor. Since the resonant frequency of the eye is dependent on the pressure therein, changes in intraocular pressure may readily be determined after a baseline pressure is established.

Method of making of compound x-ray lenses and variable focus x-ray lens assembly

Patent Khounsary, Ali

A method for producing microstructures for use for x-ray lenses using extrusion techniques and a variable focus x-ray lens assembly are provided. An elongated strip of multiple x-ray lenses and cavities of arbitrary cross-section are produced by an extrusion step. A predefined lens profile of the multiple x-ray lenses has, for example, a parabolic profile for x-ray focusing. The elongated strip of multiple cylindrical compound x-ray lenses can be cut into multiple uniform small lengths, for example, 50 mm lengths, and positioned within a support member. Cutting the assembled support member and x-ray lenses at a selected angle provides amore » variable focus x-ray lens assembly. « less
