    Abstract: A computer-implemented method, including: capturing a nominal refractive power and/or a nominal astigmatism in a near reference point of the lens, determining a corrective value of the vertical or horizontal prism in the near reference point of the lens; modifying the nominal refractive power and/or the nominal astigmatism in the near reference point on the basis of the corrective value of the vertical or horizontal prism of the lens; determining a continuous course of the nominal refractive power or the nominal astigmatism along the main line of the lens on the basis of the modified refractive power and/or nominal astigmatism in the near reference point; and calculating or optimizing the lens on the basis of the modified nominal refractive power and/or nominal astigmatism in the near reference point and the determined course of the nominal refractive power and/or the nominal astigmatism along the main line.

    Abstract: Lens holding device holding an optical lens at its edge during a dip coating in a dip coating bath. First elastic lens holder having first lens edge holder holds the optical lens at a right edge of the optical lens, second elastic lens holder with second lens edge holder holds the optical lens at a left edge of the optical lens, and a circumferential frame with a third lens edge holder holds the optical lens at a lower edge of the optical lens. The circumferential frame has first and second lateral frame portions such that when the lens holder is raised out of the dip coating bath, waves caused at a surface of the dip coating bath are damped by the right or left lens edge holder, respectively.

    Abstract: In a method for determining 3D coordinates of at least one predetermined point of an object, the object is arranged in a measurement region and a variable illumination source projects a variable pattern onto the object arranged in the measurement region. An image recording apparatus which is arranged in a previously known relationship with respect to the illumination source records an image of at least one section of the object illuminated by the variable illumination source. The at least one predetermined point is detected in the recorded image. The 3D coordinates of the at least one predetermined point are determined from the recorded image, taking into account the previously known relationship of the image recording apparatus with respect to the illumination source, if a check of the recorded image reveals that the at least one predetermined point is marked in the recorded image by a feature of the variable pattern.

    Abstract: The present invention relates to improved coloring of an optical glass, in particular of a spectacle lens, comprising a predetermined glass material, in order to obtain a target coloration of the optical glass. In this case, a method according to the invention comprises: determining a material-specific intrinsic coloration of the predetermined glass material; determining a glass thickness at a plurality of evaluation locations on the optical glass; identifying an intrinsic coloration of the optical glass from the material-specific intrinsic coloration of the predetermined glass material and the glass thickness at the plurality of evaluation locations on the optical glass; determining a reference color pigment amount for at least one color pigment in such a way that the reference color pigment amount applied on a reference substrate brings about for the reference substrate the target coloration to be obtained on the optical glass; specifying a color correction model which describes a relationship between a deviation of a color pigment amount for at least one color pigment from the reference color pigment amount of the at least one color pigment and a resultant deviation of a coloration of the reference substrate from the target coloration; and determining a target color pigment amount which deviates from the reference color pigment amount by a color pigment amount correction which compensates for the ascertained intrinsic coloration of the optical glass in accordance with the defined color correction model.

    Abstract: Adjustment of an eyeglass lens or a pair of eyeglasses by means of an individual brightness-dependent centering of an eyeglass lens. In particular, a method for adjusting an individual eyeglass lens for at least one eye of an eyeglass wearer, including: defining an individual usage situation which comprises at least one target brightness value for the light to be captured by the at least one eye; determining a position of the pupil in at least one direction of view of the at least one eye which occurs or is expected at the at least one target brightness value; determining a reference point of the eyeglass lens, in which the eyeglass lens effects a required correction of individual refraction data for the at least one direction of view; on the basis of the determined individual value of the pupil position, providing and arranging the eyeglass lens in such a manner that the at least one reference point of the eyeglass lens is arranged in front of the at least one eye of the eyeglass wearer.

    Abstract: A layer system includes at least one stack of successive multilayers, wherein each multilayer includes a first partial layer with a first optical thickness and a second partial layer with a second optical thickness that is different from the first optical thickness. The multilayer has optical characteristics that are specified depending on a parameter which is a function of a ratio of quotients of the optical thickness of a partial layer with higher refractive characteristics and the optical thickness of a partial layer with lower refractive characteristics of the respective multilayers, wherein the index i denotes the order of the successive multilayers in the stack. The product of a reflectivity of the stack of multilayers and the parameter is less than for an anti-reflection and/or anti-reflective effect of the stack of multilayers, or is greater than or equal to 1 for a mirroring. An optical element may include a layer system and a method for producing such a layer system.
