Maintenance
This chapter describes the daily and periodical inspection and maintenance
required to maintain the performance of this microscope.
㪋
4.1 Cleaning and Lubrication
(1) Main unit
Periodically apply a thin layer of grease over the slide guide surfaces and rack of the optical tube using
a brush.
(2) XY stage
Apply a thin layer of spindle oil to guide rails. After dusting the stage glass wipe it gently with a soft
cloth.
(3) Eyepiece and objective
Since the optical glass used for lenses is soft and subject to scratches, always use an air-blower or a
feather to dust the lens surface. To remove contaminants such as oil and fingerprints, gently wipe them
in a circular motion with gauze dampened in high-grade alcohol.
