Apply IPA to the surface of the lens, allow the IPA to work into the dirt and gently wipe in
one direction, then again at 90 degrees. Repeat this for both sides of the lens.

Clean the surface or lip where the lens sits inside the barrel, any dust on this surface will
cause the lens to seat incorrectly and may affect the alignment of the laser.

After cleaning, hold the edges of the lens, with the convex surface facing upward and
carefully replace it into the machined recess of the barrel.

Place the O-ring into the barrel, on top of the lens, and secure with the brass screw. Do
