  • Patent number: 10688597
    Abstract: A system uses a femtosecond laser beam to polish a surface of an optical element to optical smoothness. The system includes a fixture, a laser system, and a controller. The fixture holds the optical element. The laser system generates the femtosecond laser beam. The femtosecond laser beam includes converging laser pulses with a pulse duration less than 900 femtoseconds. The controller controls relative positioning of the surface of the optical element and the femtosecond laser beam so that a waist of the femtosecond laser beam is outside the optical element and 0.5-2.0 Rayleigh ranges away from the surface of the optical element. Also, an intensity of the femtosecond laser beam at the surface of the optical element is sufficient to ablate the surface.

    Abstract: A molded contact lens comprising a stiffer optic zone relative to the peripheral zone of the contact lens provides an optical element for correcting astigmatism without the need for or substantially minimizing the need for the correction of rotational misalignment. The higher elastic modulus optic zone vaults over the cornea thereby allowing a tear lens to form. The tear lens follows or assumes the shape of the back surface of the contact lens. The combination of the tear lens and the optical zone provide an optical element for correction of refractive error.

  • Patent number: 9465149
    Abstract: Provided is an immersion diffraction element that prevents decrease of diffraction efficiency thereof so as to satisfy optical performance. A reflection type diffraction element is made of a material transmitting a light, beam having a predetermined wavelength. An echelle diffraction grating covered with a reflecting film that prevents transmission of the light beam is formed on one surface of the material. A diffraction grating is formed off in a repeated manner, a blazed surface facing incident light and a non-blazed surface connecting the blazed surface to a neighboring blazed surface. An angle formed between the blazed surface and the non-blazed surface is an acute angle. A defect generated at a grating vertex of the blazed surface fails in a shadow of the neighboring blazed surface so as to prevent the incident light from becoming scattered light due to the defect portion.

  • Patent number: 9395470
    Abstract: A center-portion molding member having a center-portion transfer shape surface and a side wall surface is inserted and fitted in a frame-portion molding member having a frame-portion transfer shape surface to form a part of a cavity. The center-portion molding member has a groove portion in the side wall surface. The groove portion protrudes from the frame-portion transfer shape surface. Before injected resin transfers a shape of the center-portion transfer shape surface, the side wall surface of the center-portion molding member is sealed with the resin to form, between the center-portion transfer shape surface and the resin, a space in which gas is confined.

  • Patent number: 9393378
    Abstract: Among other things, there is provided a system for providing therapeutic cooling or hypothermia to localized areas of the body such as the brain. A source of compressed gas such as a medical-use oxygen canister is connected via a delivery tube to a mask fitted to a patient. The gas undergoes adiabatic cooling as it enters the delivery tube, and is provide to the patient in such cooled state. The system may be provided as a portable or ambulatory device or kit, with the delivery tube or other part easily disconnected from one compressed gas source and connected to another, for continued therapy even during transportation.

  • Patent number: 9242418
    Abstract: A process is described for manufacturing an ophthalmic lens containing a Fresnel microstructured surface inside the lens. The Fresnel lens is injection molded with a mold insert having a heat conductivity lower than the thermoplastic material used to form the Fresnel lens. A second thermoplastic material is overmolded to the Fresnel lens to cover and protect the microstructured surface. The mold insert is made from nickel or a thermoplastic material. The resulting lens includes two layers having different refractive indices. The Fresnel lens may be made from polycarbonate while the overmold may be made from a poly(methyl methacrylate) or a thermoplastic polyurethane.
