MULTI-WAVELENGTH LASER SYSTEM

A multi-wavelength laser module including a base plate, a plurality of radiation sources mounted on the base plate, at least one telescope including a first lens and a second lens wherein the second lens is arranged at a distance from the first lens along a radiation beam path, thereby creating a telescopic effect. A beam angle correction plate is arranged between the first lens and the second lens in the radiation beam path, the beam angle correction plate being angled in relation to the radiation beam path so as to parallel shift the radiation beam inside the telescope and thereby adjust the pointing direction of the radiation beam after passage of the telescope. Further, a method for assembling a multi-wavelength laser system provided with telescopes with such beam angle correction plate.
