ABSTRACT: "Optical system which provides a collimated light beam". An optical system which provides a collimated light beam, comprising a tubular holder, a semiconductor laser incorporated in the holder and furthermore a system of lenses incorporated in the holder, in which the semi- conductor laser is positioned against an abutment in the axial direction of the holder and a resilient element is placed between the system of lenses and the abutment, while on the side of the system of lenses remote from the resilient element a locking element is present which, after axial adjustment in the holder, is fixed in such a place that the system of lenses, after moving in the axial direction against the pressure of the resilient element, is in the position in which its focus coincides with the laser element in the semiconductor laser.
