Align a Laser Beam Level to the Optical Table
Two methods for aligning a laser beam so that it propagates parallel to the surface of the optical table are demonstrated.
The first technique adjusts the pointing angle of a laser, whose tip and tilt can be adjusted. Using a ruler, the laser beam is leveled and directed along a row of tapped holes in the table.
Starting with this aligned beam, the technique for changing both the direction and the height of a beam from a fixed laser source is demonstrated. Two mirrors, which are set at different heights, direct the beam along another row of tapped holes in the table. The beam is then leveled at the height of the second mirror using two irises.
Components include a PL202 laser module, KM100 kinematic mounts, AD11NT adapter, BHM1 ruler, PF10-03-P01 mirrors, and IDA25 irises.
