AMADA BREVIS #7 Cleaning the lens

While demonstrating how to remove and replace the optics, we accidentally smudged the lens. So, now it must be cleaned and we show that process (without acetone). Once the lens is cleaned, it is replaced immediately. We also take a "tape shot" to ensure concentricity when we replace the lens and attach a nozzle. This must be done any time a lens is removed and replaced.
