MICROSCOPE COMPONENTS
ARM - the vertical column (attached to the base) which supports the
stage and contains the coarse and fine adjusting knobs and focusing
mechanism.
BASE - the housing and platform of the instrument to which the arm is
attached. The base stands on rubber feet and contains the illuminator
assembly. The bulb replacement part number is printed on the
underside of the base.
COARSE FOCUS CONTROL - the larger focus control knob located on
either side of the microscope which facilitates rapid and heavy
movement of the focusing mechanism. In order to prevent gear damage,
the focus control is equipped with a slip clutch that allows slippage at
both ends of the focusing range.
COAXIAL CONTROLS (M3700 series only) – the focusing mechanism
moves the stage up and down to bring the specimen
into focus. The
coaxial focusing system combines both the coarse and fine focus into
one knob located on both sides of the microscope. The control is
designed for a continuous operation over the range of the stage
movement.
CONDENSER – the condenser is mounted in the stage and it is used in
conjunction with the iris diaphragm. The function of the condenser is to
provide full illumination to the specimen plane and to enhance the
resolution and contrast of the object being viewed. The condenser can
be raised and lowered for precise light control.
CORD HOLDER (Corded models only) - the bracket installed on the back
of the arm which is used to wrap and store the electrical cord.
DIOPTER ADJUSTMENT (M3700 series only) – located on the left
eyepiece of the binocular head and is designed to help compensate the
difference between the user’s eyes.
EYEPIECES - the upper optical element that further magnifies the
primary image of the specimen and brings the light rays in focus at the
eyepoint.
FINE FOCUS CONTROL - the fine focusing knobs, located on either side
of the microscope, in front of and slightly lower than the coarse
focusing
knobs (M3600 series) or in the center of the coaxial focusing
