    Abstract: A rod lens array is configured so that when a relation between R and r0 is set to be R?r0?0.8R, and the gradient index of the rod lens is approximate to n(r)2=n02{1?(g·r)2}, an overlap degree m, defined by m=X0/2R, is 2.55 or more and 4 or less and an aperture angle of the rod lens, represented by n0·g·r0, is 0.1 or more and less than 0.22. The array is capable of minimizing light quantity unevenness even where there may be assembly error or aged deterioration occurs. An equal-magnification imaging optical apparatus usefully includes a rod lens array.

  • Publication number: 20140172094
    Abstract: A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10° C. and 60° C., inclusive, de minimis or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.

  • Publication number: 20140168803
    Abstract: An advantageous optical apparatus with relatively large field viewing of an image to the rear of an observer is disclosed. The apparatus has two mirrors having cylindrical symmetry where the mirrors are positioned so that a plane of symmetry for each mirror is substantially coincident. The mirrors are further configured so that the apparatus has an astigmatism less than 0.0035, and a ratio between the far field and the near field magnification of less than 0.9. The apparatus is fabricated, in one embodiment, by using force to conform a thin polymer mirror onto an appropriate surface configuration on a monolithic block.

  • Patent number: 8728380
    Abstract: A lithographic method for forming a pattern within a surface on a substrate includes providing a substrate with a degradable material, molding the material to imprint a pattern thereon, depositing a layer of a second material over the imprinted pattern, removing portions of the layer of the second material to expose portions of the imprinted pattern of degradable material and removing portions of the exposed degradable material to leave an open pattern in the layer of second material.

    Abstract: An arrangement for outputting light is provided, having a plurality of punctiform light sources and a light deflection element with a boundary face and/or a boundary face section, which boundary face or boundary face section is arranged in the beam path of the light of both a first light source and of a second light source. In this context, the boundary face or the boundary face section forms a light input face for the light of the first light source into the light deflection element and at the same time forms a reflective face for the light of the second light source.

  • Patent number: 8721934
    Abstract: There is described a method of removing excess lens forming material from a molded ophthalmic lens (1), such as the peripheral region of a contact lens. In order to form a lens (1) a lens forming material is polymerized and/or cross-linked within a mold cavity of a mold comprising female and male mold halves. The mold is opened by moving the female and male mold halves apart from each other. The formed lens (1) is supported on a carrier (3) such, that a front surface (2) of the lens (1) is exposed. Residues of non-polymerized and/or non-cross-linked lens forming material are removed mechanically by contacting the exposed surface (2) of the formed lens (1) for a period of time of about 0.5 seconds to about 4 seconds, preferably about 0.8 seconds to about 2 seconds, with a cleaner (7) having a hardness which is smaller than that of the polymerized and/or cross-linked lens forming material. There is also described a device (5) for carrying out the method.

    Abstract: A method includes: a main body processing step of forming a lens main body having the concave lens surface; a molding step of coating a molding resin on the concave lens surface, pressing a microstructure forming mold, having a molding surface portion transferring the reflection preventing part formed on the surface of a deformable base body part thereof, against the concave lens surface, and curing the molding resin; and a mold release step of exerting a moment of a force relating to the surface top of the molding surface portion so as to deform the base body part to gradually separate the microstructure forming mold from an outer peripheral side thereof in a direction in which the concavo-convex shape of the reflection preventing part extends, thereby performing mold release.

  • Patent number: 8715542
    Abstract: An optical waveguide is cut by moving a heated knife blade across the optical waveguide with the knife blade maintained at a predetermined angle. At that time, by maintaining the temperature of the knife blade at a temperature not lower than the glass transition point of the optical waveguide, a portion, in contact with a bevel plane of the knife blade, of the optical waveguide softens to be planarized along the bevel plane. In this way, an optical path conversion mirror constituted of a planarized cut plane is formed in a region through which the bevel plane has passed.
