An optical module (10) having at least one beam-forming element (14) and having at least two retainer brackets (20) for fastening the optical module (10) to a carrier (30) are provided. In this connection the retainer brackets (20) have a first support element (22a) at a first spacing with respect to the lens (14) and a second support element (22b) at a second spacing different from the first spacing with respect to the beam-forming element (14) in order to selectively fasten the optical module (10) to the carrier (30) at the first spacing or at the second spacing.
