Description
mechanical stage
through which the light from the light source can
shine for the purpose of illuminating the specimen.
The specimen slides are therefore guided precisely
using the x/y mechanical stage adjustment knob.
g)
X/y mechanical
stage
Like the height adjustment of the specimen stage,
the x/y mechanical stage is equipped with a
precision mechanism, enabling the specimens to be
micrometer-precision-guided under the objective
lens even at large magnifications by virtue of the x/y
mechanical stage adjustment knob. The microscope
has a specimen clamp. The specimen slides are
clamped beneath it.
h)
X/y mechanical
stage adjustment
knob
The two adjustment knobs enable the microscope to
be operated using one hand, with the lower knob
being used for horizontal adjustment and the upper
knob for vertical adjustment.
i)
Condenser
In addition to the eyepieces, prisms and objective
lenses it is the fourth optical component of the
microscope and important for illuminating the
specimen. The specimen could not be properly
illuminated without it.
The condenser is located underneath the specimen
stage and consists of a lens system and an iris stop,
or aperture diaphragm. The condenser serves to
optimally collect the microscope light for the
respective objective lens. When the aperture is
opened, resolution increases while contrast
decreases. The opposite effect is created when it is
closed, i.e. resolution decreases while contrast
increases. Consequently, the purpose of the
condenser is to enable an optimal compromise
between resolution and contrast to be set for the
respective specimen. The aperture diaphragm has
to be readjusted every time the objective lens is
changed.
j)
Condenser
adjustment knob
Enables the condenser to be precision-raised and
lowered.
k)
Coarse and fine
adjustment knob
This knob enables the specimen stage to be height-
adjusted with micrometer precision. The coarse and
fine adjustment is featured as a separate series of
knobs, with the fine adjustment knob being smaller
than and mounted onto the larger coarse adjustment
knob. They enable the specimen to be precision-
focused.
l)
Internal lighting
source
A light source is needed to illuminate a specimen,
the light being projected through the condenser into
the specimen and then projected by this in turn into
the objective lens and the eyepiece. The
