Compound Microscope Parts
- Head/Body houses the optical parts in the upper part of the microscope.
- Base of the microscope supports the microscope and houses the illuminator.
- Arm connects to the base and supports the microscope head. It is also used to carry the microscope.

What is used to hold the microscope?
The microscope arm connects the eyepiece tube to the base.

arm
To carry the microscope, grasp the microscope’s arm with one hand. Place your other hand under the base. 2. Place the microscope on a table with the arm toward you.

- Eyepiece.
- Eyepiece Tube.
- Objective Lenses.
- Stage.
- Illuminator.
- Diaphragm or Iris.
- Coarse Adjustment Knob.
Which of the following is used to hold the glass slide in place and prevent it from moving?
Spring loaded metal clips on the microscope stage are used to hold the slide in place.
What are the parts of a microscope and what do they do?
Eyepiece Lens: the lens at the top that you look through, usually 10x or 15x power. Tube: Connects the eyepiece to the objective lenses. Arm: Supports the tube and connects it to the base. Base: The bottom of the microscope, used for support.
What are the two lenses in a microscope?
Compound Microscopes
Typically, a compound microscope is used for viewing samples at high magnification (40 – 1000x), which is achieved by the combined effect of two sets of lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample).
What are the two adjustment knobs used in focusing the specimen?
If there are only two knobs, as on the monocular microscope in Figure 4.1, those two are the coarse focus and the fine focus and you only have to keep those two separate. But if there is a third knob, it is the condenser adjustment knob. As a general rule, do NOT touch or adjust this knob.
Which part of the microscope should you hold when lifting or moving the microscope quizlet?
Used to support the microscope, you should hold a microscope by the base and this part when moving a microscope to a different location. The smaller of the 2 adjustment knobs, this is used to move the stage slightly to fine tune focus on a microscope.
What is used to secure the slide to the stage?
Stage clips hold the slides in place. If your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs.
Is used to support the microscope when carried?
ARM This part on the side of the microscope is used to support it when it is carried. COARSE ADJUSTMENT KNOB This part moves the stage up and down to help you get the specimen into view.
How do you carry a microscope?
How to carry the microscope
- When carrying the microscope, hold its arm securely with both hands.
- When carrying the microscope, do not hold the focus knobs, eyepiece tube, stage, or other components as it may result in those parts coming off and cause of trouble.
How many parts are there in microscope?
Figure: Diagram of parts of a microscope
There are three structural parts of the microscope i.e. head, base, and arm.
How does a basic 2 lens microscope work?
A compound microscope uses two or more lenses to produce a magnified image of an object, known as a specimen, placed on a slide (a piece of glass) at the base.By raising and lowering the stage, you move the lenses closer to or further away from the object you’re examining, adjusting the focus of the image you see.
Which two parts of the light microscope is used in magnify the image of an object?
Calculating the magnification of light microscopes
The compound microscope uses two lenses to magnify the specimen: the eyepiece and an objective lens.
Which part of the microscope holds the specimen slide in place?
Stage clips
Stage: The flat platform where you place your slides. Stage clips hold the slides in place.
Why are there two knobs on a microscope?
The course focus knob allows for dramatic or large movement of the objective lens. The fine focus knob allows for very slight movement of the objective lens. The stage has two metal clips to hold the microscope slide in place. The diaphragm allows light to be focused onto the specimen through a hole in the stage.
What is two adjustment knob in microscope?
Some microscope will still have the two distinct knobs with the smaller being the fine adjustment knob and the larger, the coarse adjustment knob as shown in the image. The coaxial knob allows the user to change between the knobs by feel instead of having to pull away from the eyepiece to look for the desired knob.
What supports the body tube and is used to carry the microscope?
Arm: supports the body tube and is used to carry the microscope. Base: supports the microscope and is used to carry it; the bottom part of the microscope.Stage: supports the object (microscope slide) being viewed. Stage clips: hold the microscope slide in place.
What supports the upper part of the microscope?
The arm supports the upper parts of the microscope and is used to carry the instrument. The base supports the whole microscope. The body tube holds the eyepiece on one end and the nosepiece with the objective lenses on the other end.
What is the slide secured on on a microscope?
A microscope slide is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope. Typically the object is mounted (secured) on the slide, and then both are inserted together in the microscope for viewing.
