A spectacle lens, which is manufactured by additive manufacturing, includes interspersing first volume elements and second volume elements. The first and second volume elements are arranged on the grid points of a geometric grid to form a first sub-grid and a second sub-grid, respectively. The first sub-grid forms the first part of the spectacle lens having a dioptric effect for vision for a first object distance and the second sub-grid forms the second part of the spectacle lens having a dioptric effect for vision for a second object distance, which differs from the first object distance.

Spectacle lens and method for producing a spectacle lens

A spectacle lens has, starting from the object-sided front surface of the spectacle lens to the opposite rear-side of the spectacle lens, at least a) one component A including at least one functional layer Fand/or an ultrathin glass, b) one component B including at least one polymer material and, c) one component C, including at least one functional layer F and/or an ultrathin glass. A method, in particular a 3D printing method, for producing the spectacle lens is also disclosed.

A method for demonstrating optical properties of a lens for spectacle glasses is disclosed in which a demonstration tool displays an optical property of the lens. The demonstration tool includes a light source and a light sensor receiving light from the light source. Placing a lens in the beam path between the light source and the light sensor changes the readout from the light sensor and the change in readout is converted into an optical property of the lens. An observer sees the optical property of the lens on a display.

The present invention provides a process for producing an optical waveguide () more particularly for integrated photonic systems. This process comprises provision of polymerizable material; local polymerization of the polymerizable material to produce a multiplicity of polymerized structural elements (); removal of the unpolymerized regions of the polymerizable material; and heating of the polymerized material more particularly above the glass transition temperature thereof in order to fuse the multiplicity of polymerized structural elements () together to form the optical waveguide ().

Production of 3D free-form waveguide structures

An optical system for producing lithographic structures is disclosed. Also disclosed is a method for determining relative coordinates of a position of a writing field relative to a position of a preview field in such an optical system, and a method for producing lithographic structures using such an optical system.

A polarized ophthalmic lens has a polarization gradient with a primary light transmission gradient. The lens also includes a secondary light transmission gradient, the secondary light transmission gradient being complementary to the primary light transmission gradient such that the lens exhibits uniform light transmission.

A micro-optical element includes a resonator substrate, at least one microresonator includes a rotationally symmetrical body mounted on the resonator substrate, and a light-reflecting element including a ring-shaped mirror that surrounds the rotationally symmetrical body.

Micro-optical element, micro-optical array, and optical sensor system

An opto-mechanical switch produces different optical paths from two optical path sections out of a plurality of optical path sections that are oriented in different spatial directions. The switch has an optical component on which one end of each optical path section impinges, and which is adapted to be moved linearly in a direction of movement at right angles to the optical path sections between different switching positions, in which it selectively couples different optical path sections optically with each other. Further provided is a measuring system for the analysis of fluids, having such an opto-mechanical switch.

A microoptical component for coupling a laser light to microresonators includes at least two microresonators, each having a form of an axially symmetric body disposed on a pedestal, and at least one waveguide for the laser light. The at least two microresonators are disposed on a first substrate having first side walls. The at least one waveguide is disposed on a second substrate having second side walls. The first side walls and the second side walls are fixedly joined.

Microoptical component and method for its manufacture

An optical element includes a substrate having a passive waveguide and a laser waveguide disposed therein. The laser waveguide is in direct contact with the passive waveguide over a surface of contact so as to provide a butt coupling between the passive waveguide and the laser waveguide. A step extends between an upper edge of the passive waveguide and an upper edge of the laser waveguide. A covering is disposed on the passive waveguide so that the covering and the substrate together provide a cladding of lower refractive index around the passive waveguide and so that a hollow space is disposed between a lower edge of the covering and the upper edge of the laser waveguide.
