coarse focusing knobs, are used for precise focusing adjustments once
the specimen has been brought into view with the coarse focus controls
HEAD
- it is the top portion of the microscope that contains the
refracting prisms and the eyepiece tube. The eyepiece is locked onto the
eyepiece tube with a set screw. The head rotates allowing operation of
the microscope from the front or the back, and allows the microscope to
be shared by simply rotating the head.
IRIS DIAPHRAGM
- a round multi-leaf device mounted below the
condenser which is controlled by a lever. It is similar to a camera shutter
and controls the amount of light entering the condenser, allowing the
user to control contrast. If the image is “washed out” the iris diaphragm
is opened too wide. If the image is too dark the iris is not open wide
enough.
MECHANICAL STAGE -
An alternative to stage clips is a Mechanical Stage.
A Mechanical Stage holds the slide in place, allowing the user to move
the slide on any x/y axis through the manipulation of two control knobs
or a co-axial control mechanism.
NOSEPIECE - the revolving turret that holds the objective lenses,
permitting changes in magnification by rotating different powered
objective lenses into the optical path. The nosepiece must “click” into
place for the objectives to be in proper alignment.
OBJECTIVES
- The DIN objectives are standard in the industry, with large
numerical aperture (N.A.) to permit maximum resolution. All objectives
are achromatic, color-coded and parfocaled at a 45mm distance. The
40XRD and the 100XRD are sealed to keep oil residue from seeping into
the objective. These two objectives have a spring loaded tip to prevent
accidental breakage of either the slide or front lens of the objective if
they should come into contact with each other.
