Exercise 1: Monocular Compound Microscope Flashcards
revolving structure at the lower end of the body which bears the lower lenses. This facilitates shifting of objectives.
Rotating nosepiece (revolving nosepiece)
found in the draw tube for further magnification of the image
Ocular/ eyepiece
Things seen in this way under the microscope are said to be observed by?
Transmitted light
lower lens screwed to the rotating nosepiece, serves to form a bigger image of the object, within a body tube.
High power objective
which the viewer looks at the object. Normally of 10 to 15 times magnifying power.
Eye piece or ocular
found immediately beneath the stage; serves further to concentrate the light rays of the specimen.
Condenser
Two sets of lenses
eye piece or ocular and objective lenses
Found below the stage with concave and flat surfaces to gather and direct the light to illuminate the object.
Mirror
these consists of certain precise parts chiefly of metal to support and adjust the optical parts.
Mechanical parts
Keep the slide in place for clear focusing: prevent the slide from being dislodge.
Stage clips
short supporting piece arising from the base where the arm is attached.
Pillar
platform with central aperture for light to pass through and two stage clips to hold the slide being studied.
Stage
a movable hinge between the pillar and arms and is used to tilt the upper parts whenever necessary.
Inclination joint
geared to the body tube use to bring the object into focus; uppermost and larger knobs used to raise and lower optical system in preparation for focusing when using the low power objective.
Coarse adjustment screws or knobs
smaller cylinder that is attached to the upper portion of the body tube which bears the ocular or eyepiece.
Draw tube
It possible to observe object so small that they are invisible to our unaided eyes.
Microscope
metallic structure above the nosepiece which protects the lower lenses.
Dust shield
is a hollow cylinder attached to the arm:
Body tube
lower smaller knob below the coarse adjustment screw used for slow or little movement of the body tube when focusing the high power objective and for more delicate focusing.
Fine adjustment screws
The shortest of the three objectives; use for general viewing of the specimen studied.
Scanner
mechanism attached to the stage for ease in moving the slide or moves the specimen by screw movement either forward, backward or sideward.
Mechanical stage
heavy, Y shaped foot in which the microscope stands.
Base
these consists principally of special types carefully ground and polished glasses aligned on an optical axis for the enlargement of the image of the object under study.
Optical parts
A lense that nearer to the object
Objective lenses
