2.5.5 Low-power system for 2.5x/4x
objectives mounted on the
condenser carrier
The low-power system enables full illumination of
the field of view when using a low-magnification
objective (2.5x-4x) in combination with the
condenser 0.9/1.25 H.
It can be centered and remains in the beam path
throughout the use of the corresponding objective.
•
Swing the low-power system (
721H
Fig. 2-13/
2
) in or
out of the beam path using the handle
(
722H
Fig. 2-13/
1
). Make sure the module locks in
securely.
•
Do not use the low-power system with LED
illumination for transmitted light.
ATTENTION
If the condenser carrier with mounted low-power system is moved too far down, the low-
power system may collide with the field diaphragm and damage it!
