Abstract
A device (1) for emitting light to a beam-collimating lens (3), and 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) comprises at least one biconvex collimation element (4) and is produced from silica glass, preferably by a fiber drawing process. The laser light source (2) emits visible laser light, typically having in a wavelength in the range of 400-550 nm.
