Patent number: 9223148Abstract: A multifocal lens has a number n>2 of principal powers, of which at least one principal power is refractive and at least one principal power is diffractive. The multifocal lens includes a first lens portion having at least one first annular zone and at least a second lens portion having at least one second annular zone, wherein the zones each have at least one main sub-zone and at least one phase sub-zone. For forming the n principal powers, a maximum of n?1 lens portions are combined, and an averaged refractive power of a zone of the first lens portion is equal to an averaged refractive power of a zone of the second lens portion.Type: GrantFiled: October 28, 2012Date of Patent: December 29, 2015Assignee: Carl Zeiss Meditec AGInventors: Werner Fiala, Mario Gerlach

Publication number: 20060176572Abstract: Circular and annular lens zones are disclosed which, at a given lens area, exhibit a depth of focus of a lens of considerably smaller area. The large depth of focus is achieved by imparting the lens zones a refractive power profile. An assembly of such large depth of focus lens zones represents a lens of large diameter which lens, in polychromatic light, exhibits essentially the same depth of focus as the lens zones from which it is composed.Type: ApplicationFiled: June 29, 2004Publication date: August 10, 2006Inventor: Werner Fiala

Patent number: 6536899Abstract: A multifocal lens including annular zones wherein each annular zone is divided into at least two annular sub-zones. Preferably, no geometric or optical optical steps are present between annular zones or annular sub-zones. The refractive powers within the annular sub-zones are chosen such that the lens exhibits at least two diffractive powers and that at least one of those diffractive powers substantially coincides with the average refractive power of each annular zone.Type: GrantFiled: July 11, 2000Date of Patent: March 25, 2003Assignee: Bifocon Optics GmbHInventor: Werner Fiala

Patent number: 6120148Abstract: A multifocal diffractive lens includes at least two annular zone lenses. Provided between adjacent annular zone lenses is an optical step. Each annular zone lens exhibits a refractive power profile D.sub.g,i (r) wherein i is any i-th annular zone lens and r is the distance between an axis of the diffractive lens and a point on a back surface of the lens. The lens is further characterized in that an average power of zones i,j . . . are given by D.sub.av,i, D.sub.avj . . . respectively, and optical path lengths of light rays extending from an object point to a conjugated image point are different by the optical step for light rays transmitting through adjacent annular zone lenses. The annular zone lenses are shaped and positioned such that all of the average refractive powers D.sub.av,i, D.sub.avj . . . are substantially equal to a single value, D.sub.av.Type: GrantFiled: October 5, 1998Date of Patent: September 19, 2000Assignee: Bifocon Optics GmbHInventors: Werner Fiala, Johann Pingitzer

Patent number: 5000676Abstract: Process for heating a catalyst used for the catalytic high-temperature oxidation of a mixture of a combustible gas and air or oxygen which is introduced in the cold state. The mixture is ignited on the input side at a point which is so close to the catalyst that the mixture is burning when it reaches the surface of the catalyst.Type: GrantFiled: May 23, 1989Date of Patent: March 19, 1991Inventor: Werner Fiala

Patent number: 4373225Abstract: A piping valve for conduits conveying pressurized viscous material, such as concrete, provides a means for introducing a wiper into the conduit for cleaning purposes. The piping valve has a reciprocally displaceable part with a transmission pipe and a pipe chamber containing the wiper. The reciprocally displaceable part may be moved between a first position in which it is aligned with the conduit and a second position in which it receives the wiper for passage through the conduit.Type: GrantFiled: July 1, 1980Date of Patent: February 15, 1983Assignee: Friedrich Wilh.
