A computer-implemented method for generating printing instructions for inkjet printing a spectacle lens, wherein the printing instructions are based on a digital twin of the spectacle lens, the digital twin being sliced into a layer stack. The method includes the steps of 1) positioning a volume element in a discrete x, y, z. . . x, y, zposition of a layer of the layer stack, based on a positioning of a volume element in a discrete x, y, z. . . x, y, zposition of an adjacent layer of the layer stack; or 2) not positioning a volume element in a discrete x, y, z. . . x, y, zposition of a layer of the layer stack, based on a positioning of a volume element in a discrete x, y, z. . . x, y, zposition of an adjacent layer of the layer stack.

Method for inkjet printing a spectacle lens

A computer-implemented method for calculating a digital twin of a spectacle lens is provided to use the digital twin for a manufacture of the spectacle lens. The digital twin has a predefined power distribution and contains a layer stack with a plurality of individual layers, each layer having a non-uniform layer thickness with a spatial variation and a uniform refractive index. The method includes determining the spatial variation of the layer thicknesses of the individual layers to achieve the predefined power distribution by a spatial control of optical path lengths.

A dynamic imaging system of an endoscope that adjusts path length differences or focal points to expand a usable depth of field. The imaging system utilizes a variable lens to adjust the focal plane of the beam or an actuated sensor to adjust the detected focal plane. The imaging system is thus capable of capturing and adjusting the focal plane of separate images captured on separate sensors. The separate light beams may be differently polarized by a variable wave plate or a polarized beam splitter to allow separate manipulation of the beams for addition of more frames. These differently focused frames are then combined using image fusion techniques.
