1.2 Objective Lenses
The microscope is equipped with four objective lenses which are mounted to a rotating turret between the head and the
specimen stage. Should the lenses be removed for transport, they are mounted and unmounted by rotating each lens
clockwise or counter-clockwise respectively. The lenses are typically mounted in order from 4X to 100X, but can be inter-
changed as desired. This microscope is compatible with DIN-standard objective lenses, which allows aftermarket lenses
to be used as needed. These lenses must comply with the following DIN* specifications:
•
20.32mm RMS mounting thread
•
160mm mechanical tube-length
•
45mm parfocal distance
*DIN stands for Deutsches Institut für Normung which is a German standards organization. Microscopes and objective
lenses which are DIN compliant will use the aforementioned specifications.
