Device for the superposition of beam pencils, which originate from a plurality of individual radiation sources, in at least one imaging spot as well as a device for the division of the radiation emanating from a radiation source, in separate beams

摘要

Device for the superposition of beam pencils,the start of a plurality of individual radiation sources, in at least one imaging spot, wherein the individual radiation sources in the manner of a raster are arranged, the at least one linear row of individual radiation sources, along which the individual radiation sources in a plane perpendicular to the optical axis at a distance from one another are lined up,characterized in that it comprises:a mirror channel (5; 105; 205) and a on the object side, the front of the imaging optical system (4; 104; 204), which is applied in such a way that they can function without the mirror channel, the grid of individual radiation sources (l1 to l3 ''l₁₀₁ to l₁₀₇ L₂₀₁ to l₂₀₅) in an image plane (6; 106; 206) in a corresponding grid of images (l1 ''to l3'') are mapped,whereinthe mirror channel (5; 105; 205) at least two mirror surfaces extending symmetrically with respect to the optical axis in the direction of which are spaced from each other without along. of the mirror channel (5; 105, 205) the images (l1 ''to l3'') of the forming the linear series..
