The invention relates to a device (1) for emitting light, to a beam-collimating lens (3), and to a method for producing a beam-collimating lens (3). The device (1) comprises at least one laser light source (2) and a beam-collimating lens (3), in particular for fast axis collimation, the beam-collimating lens (3) comprising at least one biconvex collimation element (4) and being produced from silica glass, preferably in a fiber drawing process. The laser light source (2) emits visible laser light, in particular in a wavelength range of 400-550 nm. 本发明涉及一种用于发射光的装置(1)、一种光束准直透镜(3)以及一种用于制造光束准直透镜(3)的方法。装置(1)包括至少一个激光光源(2)和光束准直透镜(3)，特别地用于快轴准直，光束准直透镜(3)包括至少一个双凸面准直元件(4)并且由石英玻璃制成，优选地在纤维拉制工艺中。激光光源(2)发射可见激光，特别地在400-550nm的波长范围内。
