3. Changing Optical Paths
This microscope has three ports; the eyepiece tube port (circular dovetail groove) for
mounting the eyepiece tube, the front port (F mount) for mounting a 35mm SLR
camera, and the side port (C mount) for mounting a photomicrographic attachment
or any other devices. Use the optical path changeover dial on the right side of the
microscope base to switch the optical paths between these ports.
• Only the front port has 2.5 x intermediate magnification.
• The eyepiece tube for the erect type microscope and any other devices may be
mounted on the eyepiece tube port by using the eyepiece tube bracket (option).
(For example, a teaching head or drawing tube may be mounted.)
• Various devices may be mounted to the side port. The mounting may be direct,
or indirect via the C-mount adapter. (For example, a photomicrographic
attachment, TV system, or photometry system may be mounted.)
