The method of claim 1, wherein the collimator layers are aligned and glued such that surfaces of the absorber walls are embodied flat. 3. The method of claim 2, wherein the holder structure extends beyond the lattice structure. 4. The method of claim 2, wherein the holder structure, after the gluing of the collimator module, is at least partly separated. 5. The method of claim 1, wherein the holder structure extends beyond the lattice structure. 6. The method of claim 1, wherein the holder structure, after the gluing of the collimator module, is at least partly separated. 7. A method for manufacturing a collimator bridge including at least one first collimator module manufactured in accordance with the method of claim 1 and at least one second collimator module manufactured in accordance with the method of claim 1, the method comprising:gluing the at least one first collimator module and the at least one second collimator module to one another, wherein peripheral absorber walls of the at least one first collimator module and of the at least one second collimator module are glued to one another. 8. The method of claim 7, wherein a second collimator layer of the at least one first collimator module includes a peripheral positioning element, and wherein the at least one first collimator module is positioned relative to the at least one second collimator module by the positioning element. 9. The method of claim 7, further comprising:aligning the at least one first collimator module and the at least one second collimator module in relation to one another on the first holder tool or on a second holder tool by at least one part of the holder structure, wherein peripheral absorber walls of the aligned at least one first collimator module and of the aligned at least one second collimator module are substantially congruently glued to one another. 10. The method of claim 9, wherein the collimator bridge is embodied for collimation of rays for a radiation detector rotatable around an axis of rotation of the radiation detector, wherein the first at least one collimator module and the second at least one collimator module are disposed in relation to one another so that the collimator bridge has a curvature along a direction of rotation of the radiation detector. 11. A collimator bridge, manufactured according to the method of claim 7. 12. A collimator for a radiation detector, rotatable around an axis of rotation, wherein a number of collimator bridges manufactured according to the method of claim 7 are connected to one another along a direction of rotation of the radiation detector. 13. A collimator as claimed in claim 12, wherein the collimator bridges are connected to one another such that the collimator has a curvature along the direction of rotation. 14. A tomography device with the collimator for collimating x-rays of claim 12. 15. A method for manufacturing a collimator bridge including at least one first collimator module manufactured in accordance with the method of claim 1 and at least one second collimator module manufactured in accordance with the method of claim 1, the method comprising:gluing collimator layers, assigned to the at least one first collimator module and to the at least one second collimator module, alternately such that peripheral areas of the collimator layers assigned to the at least one first collimator module and to the at least one second collimator module are glued to one another. 16. The method of claim 15, wherein a second collimator layer of the at least one first collimator module includes a peripheral positioning element, the method further comprising:positioning, via the positioning element, the second collimator layer relative to a third collimator layer of the at least one second collimator module. 17. The method of claim 16, further comprising:aligning the collimator layers, assigned to the at least one first collimator module and the at least one second collimator module, to one another at the first holder tool or at a second holder tool via at least a part of the holder structure, wherein peripheral areas of the aligned collimator layers are glued to each other as congruently as possible. 18. The method of claim 15, further comprising:aligning the collimator layers, assigned to the at least one first collimator module and the at least one second collimator module, to one another at the first holder tool or at a second holder tool via at least a part of the holder structure, wherein peripheral areas of the aligned collimator layers are glued to each other as congruently as possible. 19.
