• the contact section 16 can therefore be formed by a radial expansion of the contact layer 3 (compared to the remaining areas of the contact layer 3) or represent such, which extends in the circumferential direction around a certain area of the edge of the substrate element body, i.e. H. e.g. B. by at least 10%, extending circumferentially around or along the edge of the substrate element body 14.
• the contact section 16 can be applied directly to the top or bottom of the substrate element body 14; In the area of the contact section 16, there does not have to be a corresponding transparent, electrically conductive layer or coating.
• the edge of the substrate element body 14 can have a flattening 17.
• the flattening 17 can in particular be defined by a straight line L or a corresponding secant S running through two points P1, P2 on the edge of the substrate element body 14 forming the outer circumference of the substrate element body 14.
• the shape of the substrate element body 14 therefore does not have to represent a complete circular disk, since the edge of the substrate element body 14 can have a corresponding flattening 17.
• the flattening 17 can equally simplify the structural integration of the electrochromic arrangement into a long-range optical arrangement 9, for example as the flattening 17 can be used to prevent the electrochromic arrangement 1 from rotating in an optical tube 10 of the long-range optical arrangement 9.
• the flat 17 can form a functionalized interface of the electrochromic arrangement 1, as, as will become apparent in connection with the exemplary embodiment according to FIG. 4, a special electrical contacting option for the electrochromic arrangement 1 with an electrical power supply can be realized in this way.
• the contact section 16 is arranged or designed opposite the flat 17.
• the contact section 16 and the flat 17 can therefore be arranged or designed (essentially) offset by 180° in the circumferential direction with respect to the circular disk-like or circular-shaped basic shape of the substrate element body 14.
• the contact section 16 is arranged or formed at the top and the flat 17 is arranged or formed opposite at the bottom.
• the electrochromic arrangement 1 has two correspondingly configured substrate elements 2, each of which has a substrate element body 14 with a corresponding flattening 17 and a contact section 16 arranged or formed opposite the flattening 17.
• the substrate element bodies 14 of the first substrate element 2 and the second substrate element 2 are arranged one above the other, with their contact layers 3 facing each other, but cannot electrically contact each other to avoid short circuits.
• the respective contact layers 3 can lie one above the other in such a way that they can complement each other to form a closed ring; therefore, the contact layer 3 arranged or formed on the substrate element body 14 of a first substrate element 2 (e.g. the upper substrate element in FIG.
• a first electrical contact element can connect the contact section 16 of the contact layer 3 of a first substrate element 2 (e.g. the upper substrate element in FIG. 4) to the electrical power supply and a second electrical contact element can connect the contact section 16 of the contact layer 3 of a second substrate element 2 ( e.g. the lower substrate element in Fig. 4) with the electrical power supply.
• FIG. 5 shows a schematic representation of a long-range optical device 9 according to an exemplary embodiment in a side view. Shown purely schematically is an optical tube 10, which comprises an objective 11 nm comprising one or more objective lenses (not shown) and an eyepiece 12 comprising one or more eyepiece lenses (not shown).
• the electrochromic arrangement 1 is structurally integrated in the optical channel or tube 10 of the long-range optical arrangement 9, which extends between the objective 11 nm and the eyepiece 11; The electrochromic arrangement 1 can therefore be arranged or formed in the optical channel or tube 10 of the long-range optical arrangement 9.
• the long-range optical device 9 can be one, e.g. B. as a display, designed optical output device 18 for outputting optical information.
• the optical information that can be output via the optical output device 18, i.e. H. e.g. B. alphanumeric symbols, graphics, images, videos, etc., can be used via a, e.g. B. formed by a prism arrangement comprising one or more prisms or via a film arrangement (not shown in each case) or such a comprehensive coupling device can be coupled into the optical channel of the long-range optical device.
• the electrochromic arrangement 1 can be assigned directly or indirectly to the optical output device 18, so that z. B. the brightness and / or the contrast of the optical information that can be output via the optical output device 18 can be specifically changed via the electrochromic arrangement 1.
• FIG. 5 there is also an electrical power supply integrated into the long-range optical device 9, e.g. B. in the form of a battery, indicated.
• the electrical power supply 19 voltages can be applied to the electrochromic arrangement 1 in an automated manner by means of an assigned hardware and/or software implemented control device (not shown) or by the user by means of an assigned actuating device (not shown), which leads to a corresponding change in the transmission .
• the method comprises at least the steps, which can optionally be carried out several times: a) providing at least one substrate element 2, e.g. B. with a substrate element body 14 having a circular disk-like or -shaped basic shape; b) applying a contact layer 3 made of an electrically conductive material, which runs at least in sections around the edge of the substrate element body 14, to the top or bottom of the substrate element body 14 by a chemical and/or physical application method; c) arranging or forming at least one electrically conductive element on the substrate element body 14 to form an electrically conductive layer or coating 4; d) Arranging or forming at least one electrochromic element formed by or comprising an electrochromic material on the substrate element body 14.
