Abstract
A laser module includes a main body having a first end, a second end, and a bore connecting the first and second ends, the bore having a rotational axis that is transverse to the bore. The laser module also includes a laser beam generating device retained in the bore for producing a laser beam, a collimating lens installed in the bore between the first and second ends for collimating the laser beam into a parallel laser beam, a cylindrical lens for receiving the parallel laser beam and projecting a linear laser beam, and a cylindrical lens holder rotationally connected with the first end of the main body about the rotational axis of the bore. The cylindrical lens holder is pivoted about the rotational axis to adjust the inclination of the parallel laser beam directed onto the cylindrical lens.
