RED 200 SERIES
3.2 Operation of the biological microscope
3.2.1 Interpupillary distance adjustment
• While looking through the microscope, grasp the
eyetubes and move them on their hinges until the two
circular fields in the observation field coincide with
each other. (Figure 5)
• If several people will be using the same microscope,
each user can record the correct interpupillary distance
for them from the scale. The microscope can then be
quickly reset to the correct distance.

3.2.2 Setting bright field illumination
The RED200 Series biological microscope has been set already before delivery and can be adjusted as follows:
• Put the specimen on the stage and fix it with the slide clips. Note: The thickness of the cover slip should be 0.17 mm.
• If the biological microscope is provided with slider for phase contrast or dark field, first pull it out from the left.
• Final brightness should be set for the objective and magnification being used.
• Open the condenser aperture diaphragm to the position matching the numerical aperture of the objective.
• Lower or raise the condenser to locate the best illumination for the field.
• Rotate the brightness control to the desired intensity.
