E. Adjusting diopter (only for model F-1125).
This model has a dual head, i.e. with two head
holder tubes: one inclined, and the other vertical.
This permits use by two people at the same time.
1. To use the inclined eyepiece tube, focus on
sample using the coarse (12) and fine focus
knobs (13).
2. To compensate for the difference in vision of
the two observers, the user of the vertical
eyepiece tube can adjust focus by turning the
diopter adjustment collar. (Fig. 2).
F. Adapting a camera (only for model F-1125).
These are general guidelines on how to install a photographic or video camera to the vertical
eyepiece tube. You should know, however, that each model of camera has its own specific
instructions, and may be installed in a distinct manner.
There exist different types of adapters to install a camera on a microscope. In some of them the
eyepiece must be removed, whilst for others it is not necessary.
1. To remove the eyepiece, find the tiny locking screw (Fig. 3) on the eyepiece tube, between
the eyepiece and the diopter adjustment collar. With a watchmakers screwdriver, loosen the
screw until the eyepiece can be removed, without removing the screw.
2. Do not loosen any of the three screws on the diopter adjustment collar.
