ARM
The frame that connects the head and the base of the microscopes. It also houses the illumi-
nation switch, carrying handle, stage ring, coaxial focus controls, and the incident (top) light.
COMBI FOCUS
The coaxial focusing system combines both the coarse and fine focus into one focusing
knob located on both sides of the microscope.
DIOPTER ADJUSTMENT
Located on the left eyepiece tube of the SILVER30 Series. This adjustment is used to fine
focus the optics to compensate for visual differences between the user’s eyes.
BOTTOM ILLUMINATOR
This is the light source mounted in the base to provide transmitted illumination.
EYEPIECE
The upper optical element that further magnifies the primary image of the specimen and
brings the light rays in focus at the eyepoint.
EYEPIECE TUBE
This is the part of the head that holds the eyepieces in place. Set screws in the eyepiece
tubes can be used to lock the eyepieces in place.
STAGE CLIP
Used to hold specimen in place.
FOCUSING CONTROL KNOB
The focusing control knob located on either side of the stand are used to raise or lower the
head to bring the specimen into focus. The control knobs incorporate a slip clutch system
which prevents the head from traveling past both ends of the focusing range. When the
focusing limit is reached, the clutch system begins to slip to prevent gear damage.
HEAD
The 360˚ rotatable component that contains all of the optical elements of the stereo micro-
scope including the eyepieces, refracting mirrors and objective lenses. The head of the
SILVER30 series is designed to allow users to adjust the interpupillary distance of the
eyepieces for proper viewing.
