|
Binocular
|
|
|
holds the ocular
|
Body Tube
|
|
|
a turretlike circular mechanism rotates so that different lenses can be selected
|
Revolving Nose piece
|
|
|
each of the lens sets attached to the revolving nose piece
|
objective
|
|
|
used for initial location of the specimen
|
4x
|
|
|
used for observing specimen that don't need greater magnification
|
10x
|
|
|
used for specimen requiring greater magnification
|
40x
|
|
|
used for magnifying extreme small specimen
|
100x
|
|
|
specimen usually mounted in a glass or plastic
|
Microscope Slide
|
|
|
if the stage has an adjustable bracket that moves the slide around mechanically by rotating the positioning knobs
|
Mechanical Stage
|
|
|
is determined by multiplying the power of the ocular by the power of the ocular in use
|
Total Magnification
|
|
|
this is where the slide is held and must be moved by hand.
|
Stage Clips
|
|
|
light rays from the lamp travel through a hole in the stage, through the specimen mounted on a slide, then through the objective and ocular, to the eye.
|
Lamp
|
|
|
a lens that concentrates light, may be found between the lamp and the stage.
|
Condenser
|
|
|
sometimes the light from the lamp is too strong to see the specimen clearly. The light level may be reduced by adjusting the light intensity
|
Diaphragm
|
|
|
a rotating disk with holes of different diameters.
|
Disk Diaphragm

|
Arm
|
|
|
the scope is supported by a square or horseshoe-shaped
|
Base
|
|
|
are on the arm; these knobs adjust the distance between the stage and objective, thus focusing an image of specimen
|
coarse-focus knobs and Fine-focus knobs
|
|
|
changes the distance very little, whereas the coarse-focus knob changes the distance greatly.
|
Fine-focus knob
|
|
|
are used to make specimen or some of its partd more visible.
|
Stain
