The invention concerns a lidar unit (10), in particular a laser scanner, for laser-based distance measurement for a vehicle, with a transmitter module (12) that is designed to emit a laser beam, and a receiver module (14) that is designed to receive a reflection of the emitted laser beam, wherein the lidar unit (10) has a mounting element (16) for attaching the transmitter module (12) and the receiver module (14), the mounting element (16) and the transmitter module (12) comprise corresponding first stop surfaces (26, 28) for aligning the transmitter module (12) on the mounting element (16), the mounting element (16) and the receiver module (14) comprise corresponding second stop surfaces (32, 34) for aligning the receiver module (14) on the mounting element (16), the transmitter module (12) is pre-calibrated in relation to its first stop surface (26) and the receiver module (14) is pre-calibrated in relation its second stop surface (32). The invention also concerns a method for the assembly of a lidar unit (10), in particular a laser scanner, for laser-based distance measurement for a vehicle.
