Cleaning Objectives
Caution:
The objective may not be unscrewed during
cleaning. If damage appears on inner sur-
faces, the objectives must be sent to your
Leica subsidiary for repair. We also advise
against cleaning the inside surfaces of the
eyepieces.
The front lenses of objectives are cleaned as
described under “Cleaning Glass Surfaces”.
The upper lens is cleaned by being blown off
with a pneumatic pump.
