An apparatus () for collimating a light ray field (), a diode laser, the use of a collimation lens system (), a collimation method and a method of producing a collimation apparatus. The apparatus () collimates a light ray field (L), which diverges more quickly in a first direction (F), perpendicular to the emission direction(s), than in a second direction (S), perpendicular to both the emission direction(s) and the first direction (F). The apparatus () comprises at least one first collimation lens system () for collimating the light ray field (L) in the first direction and at least one second collimation lens system () for collimating the light ray field in the second direction. The first collimation lens system () comprises a glass cylindrical lens () with an at least partly circular profile (). The first collimation lens system () comprises an aspherical plastic lens element ().
