Lens cleaning

Notes: Always wear gloves and only handle the lens by the edges.

Isopropyl alcohol, REAGENT GRADE, is the only recommended cleaning solvent. Gently clean both sides

of the lens with clean, canned air to remove loose dust and debris.

1. Clean both sides of the lens, using a new lens wipe for each pass. Apply a few drops of Isopropyl alcohol to

the edge of the lens wipe and slowly pull it across the surface with gentle pressure. Discard the wipe after one

use.
