1. Lens/Mirror Cleaning: This part of the experiment teaches the proper way of cleaning lenses and mirrors by using lens papers and several solvents. 

2. Laser Alignment: This experiment is divided into two parts. The first part of the experiment is to align a red laser beam into two longitudinally separated apertures by using two orthogonally tuned mirrors. The second part of the experiment is to co-propagate a green laser with the pre-aligned red laser beam.
