摘要： An ophthalmic lens exhibiting diffractive power has a plurality of diffractive zones and smooth surfaces. The zones are arranged such that R.sub.0.sup.2 does not equal R.sub.1.sup.2 -R.sub.0.sup.2 where R.sub.0 is the radius of the central zone and R.sub.1 is the radius of the first annular zone.

摘要： A multifocal ophthalmic lens includes first and second lens members. Each lens member has a smooth outer surface and an inner surface with an edge about its perimeter. A multifocal diffractive zone plate on at least one of the lens members is characterized by an index of refraction. The lens members are joined at the edges by ultrasonic welding to form a cavity adjacent the diffractive zone plate. The cavity is filled with a liquid medication having an index of refraction which is different than the index of refraction of the diffractive zone plate. A hole through one of the lens members functions as a fluid transport mechanism to permit transfer of the medication between the cavity and eye.

摘要： A luminaire and method are provided comprising a light source, a plurality of prisms, such as linear prisms, for redirecting light from the light source in a predetermined direction, and a reflector for redirecting light from the light source toward the plurality of prisms. Each of the linear prisms has a longitudinal axis and the light source has a longitudinal axis, wherein the longitudinal axes of the linear prisms are substantially parallel to the longitudinal axis of the light source. Each of the plurality of prisms has an included angle, which can vary as a function of the distance from the light source. The angle can vary stepwise or continuously. In one embodiment, each of the plurality of prisms adjacent the light guide has an included angle in the range of between about 35 and 45 degrees. In another embodiment, the included angle is substantially uniform among the prisms. The luminaire optical sheet can be made out of continuous sheet with built in hinge points to provide a complete light redirecting structure.

摘要： A diffractive lens has a plurality of diffractive zones at least one of which has an optical step having an optical height equal to j.lambda. and at least one of which has an optical step having an optical height equal to k.lambda. where .lambda. is a design wavelength of the lens and j and k are unequal nonzero integers. Alternatively stated at least one of the optical steps induces a relative phase shift of 2j.pi. at the back conjugate point between two light rays emerging from a point source at the front conjugate point and striking the lens immediately on opposite sides of the step and at least one of the steps induces a relative phase shift of 2k.pi. at the back conjugate point between two light rays emerging from a point source at the front conjugate point and striking the lens immediately on opposite sides of that step.

摘要： A luminaire is provided which includes a light source, a light guide that receives light radiating from the light source, and a plurality of prisms adjacent the light guide that redirect the light from the light guide substantially perpendicular to a longitudinal axis of the light guide. The prism angles, in one embodiment, are 25°-90°-65°. The fine pitch prism arrays preferably alternate or flip-flop every few millimeters, for example, one to two millimeters to create the visual appearance of bright and dark bands which cause the structure to appear like macro prisms.

摘要： A diffractive mirror has a plurality of diffractive zones at least one of which has an optical step having a height equal to j.lambda./2 and at least one of which has an optical step having a height equal to k.lambda./2 where .lambda. is a design wavelength of the mirror and j and k are unequal nonzero integers. Alternatively stated at least one of the optical steps induces a relative phase shift of 2j.pi. at the image point between two light rays emerging from a point source at the object point and striking the lens immediately on opposite sides of the step and at least one of the steps induces a relative phase shift of 2k.pi. at the image point between two light rays emerging from a point source at the object point and striking the lens immediately on opposite sides of that step.
