 Torque adjustment of the focus knobs
To adjust the torque of the focus knobs, turn the right and left
focus knobs in opposite directions. Adjust the torque to an
appropriate level.
Notes on the torque adjustment
When the torque is too low, the zooming body may slide down due
to the various loads it carries, such as its own weight or the load of
the counterbalance spring inside the focus unit. This may result in
injury, such as pinching fingers between the objective and sample,
or cause damage to the sample or objective. Be sure to adjust the
torque to an appropriate level.
* A C-LSL2 LED Epi Illuminator 2 can be attached to the
C-FMBN Focus Mount directly or via an SMZ-U Epi Arm or a
G-EIA Flexible Arm.
* A nosepiece cannot be used together with a zooming body
combined with a FMBN Focus Mount.
* The C-FMBN Focus Mount has an antistatic function.
