Abstract (en)
[origin: WO2017060417A1] The invention relates to a lens component of an optical rain sensor (10), comprising transmitter lens (16) designed as a Fresnel lens, and a receiver lens (18) designed as a Fresnel lens, both of which, in top view, have a rectangular contour having first edges, and second edges extending at a right angle thereto. The center point (Ms) of the transmitter lens (16) and/or the center point (ME) of the receiver lens (18) is arranged eccentrically with regard to the lateral length of at least one of the edges (6), and the transmitter lens (16) and the receiver lens (18) are arranged side by side. The lens component (12) is produced using a molding process, in which a first and a second mold insert, each having a Fresnel lens shape, are arranged side-by-side, wherein the first and the second mold insert are arranged optionally rotated in each case by 0° or by 180°, and the mold inserts arranged in such a way form a negative form for the transmitter lens (16) and the receiver lens (18) of the lens component (12) during molding. In this way, a modular system for producing optical rain sensors (10) having lens components (12) is generated in a plurality of different configurations, which differ from one another with regard to the distance of the center points (MS, ME) of the transmitter lens (16) and the receiver lens (18). In order to produce the lens component (12), the mold inserts are arranged optionally rotated in each case by 0° or by 180°, and are molded using a suitable plastic. This is done in a tool for producing a lens component (12) having a receptacle, in which the mold inserts can be placed next to one another along the second edge, wherein the first and/or the second mold insert, each rotated by 0° or by 180°, can be inserted into the receptacle (44).
