Q

Total Magnification=

A

magnification of objectives (x10)

24
Q

It is used to adjust the lateral separation of the eyepieces for each individual.
When it is properly adjusted, the user should be able to focus both eyes comfortably on the specimen and visualize one clear image.

A

Interpupillary Control

25
Q

It connects the eyepieces with the objective lens. The standard length is 160 mm, which, functionally, is the distance from the real image plane (eyepieces) to the objective lenses.

A

Optical Tube

26
Q

This provides a structural site of attachment for the / holds the revolving nosepiece.

A

Neck / Arm

27
Q

It is the main vertical support of the microscope.
The stage assembly, together with the condenser and base, is supported by the stand.

A

Stand

28
Q

Holds the objectives and allows for easy rotation from one objective lens to another.

A

Revolving Nosepiece

29
Q

Supports the prepared microscope slide.

A

Stage

30
Q

Adjustments can be incorporated into one knob or can be two separate controls

A

Focus Controls / Adjustments

31
Q

May be permanently mounted or vertically adjustable with a rack-and-pinion mechanism.
It gathers, organizes, and directs the light through the specimen.

A

Condenser

32
Q

It is located under the stage, which moves it along an x- or a y-axis.

A

Stage Controls / Stage X-Y Adjustment Knobs

33
Q

It is located below the condenser within the base.
and should always be open; when it is open, it allows a maximally sized circle of light to illuminate the slide.
