Abstract

The invention relates to an optical system comprising a semiconductor laser and an optical instrument collimating the laser light. In accordance with the invention, the semiconductor laser and the optical instrument are accommodated in separate holders which are adjusted relative to one another in such a way that a criterion relating to the laser light is optimally fulfilled. After completion of the adjustment, the two holders, both forming the external housing of the entire system, are joined to one another.
