Abstract: A device (1) for producing a photoactive system (10), in particular a deactivated photoactive system (10), characterised by: an imaging device (2) having at least one imaging arrangement (20), wherein the at least one imaging arrangement (20) has a beam passage plane (SE) and an optical axis (O), and the at least one imaging arrangement (20) is designed to generate electromagnetic beams which extend along a beam path and pass through the imaging arrangement (20) on the beam passage plane (SE) and to reflect the electromagnetic beams along the beam path at the photoactive arrangement (11) in order to image, on a first focal plane (B1) of the imaging arrangement (20), an evaluation image of a photoactive arrangement (11) of the photoactive system (10) to be produced, and the electromagnetic beams of the beam path are captured on the first focal plane (B1) in order to capture the evaluation image of the photoactive arrangement (11); and a first holding device (3a) having a first holding plane (Ha), on the first

Abstract: In a method for aligning a polarization-maintaining optical fiber, in which the optical fiber (7a, 7b, 7c) is held in clamping fashion by means of a clamping device (12, 19, 23), a given rotational position of the optical fiber (7a, 7b, 7c) about the fiber longitudinal axis is detected, and the optical fiber (7a, 7b, 7c) is rotated about the fiber longitudinal axis by means of the clamping device (12, 19, 23), it is proposed that at least one clamping element (13, 14, 20-22, 24-27) of the clamping device (12, 19, 23), said clamping element abutting against the optical fiber (7a, 7b, 7c), is moved relative to at least one further clamping element (13, 14, 20-22, 24-27) of the clamping device (12, 13, 17), said at least one further clamping element likewise abutting against the optical fiber (7a, 7b, 7c), for the purposes of rotating the optical fiber (7a, 7b, 7c). Moreover, a correspondingly configured apparatus is presented.

Abstract: The invention relates to an electrode assembly (110), which comprises a layer structure with at least one first electrode (112), at least one second electrode (130) and at least one separator (116) inserted between the first electrode (112) and the second electrode (130). The first electrode (112) has here at least one first conductive band (114), the first conductive band (114) being folded in a first zigzag fold, the first zigzag fold having the effect of forming a plurality of first layers (120, 122) lying one over the other and first folding edges (134, 136) that lie opposite one another of the first zigzag fold defining a first folding direction (138) of the first zigzag fold.
