Eyepiece which contains a lens to magnify an image 10x that projected by the objective lens. Connects the Ocular Lens to the Objective Lenses and provides alignment to direct the light from the specimen into the viewer’s eye. You just studied 19 terms!
What are the parts of the microscope and their functions?
These parts include:
- Eyepiece – also known as the ocular.
- Eyepiece tube – it’s the eyepiece holder.
- Objective lenses – These are the major lenses used for specimen visualization.
- Nose piece – also known as the revolving turret.
- The Adjustment knobs – These are knobs that are used to focus the microscope.
What are functions of microscope?
A microscope is an instrument that is used to magnify small objects. Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell, its nucleus, mitochondria, and other organelles.
What is the function of the objective lenses quizlet?
The function of the objective lenses is to magnify the specimen & to produce a magnified real inage.
What is the function of the microscope diaphragm quizlet?
Diaphragm is sometimes under the stage, sometimes above light source. Supports the weight of the microscope. Contains the electronics and the light source. An electric source of illumination or a mirror used to direct light upward.
What are parts of microscope?
The three basic, structural components of a compound microscope are the head, base and arm.
- 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.

What is the function of a microscope slide?
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.
What does a microscope do quizlet?
How do microscopes work? Use lenses to magnify the image of an object by focusing light or electrons.
What is the function of the ocular on a microscope?
The eyepiece, or ocular lens, is the part of the microscope that magnifies the image produced by the microscope’s objective so that it can be seen by the human eye.
How does the lens function in the microscope quizlet?
The purpose of the condenser lens is to focus the light onto the specimen. Used to vary the intensity and size of the cone of light that is projected upward into the slide. Large, round knob on the side of the microscope used for focusing the specimen; it may move either the stage or the upper part of the microscope.
Which of the following is the most important function of the microscope?
The function of the microscope is to resolve, or distinguish, fine detail which our eyes alone cannot perceive. This cannot be done unless there is sufficient visibility, or contrast, which describes the magnitude of the differences in the image between the features of the image and its background.
How important is knowing the parts and function of the microscope?
Knowing the names of the different parts of a microscope is important because it helps you communicate clearly with students or colleagues. Remembering the different parts is easy if you keep a labeled diagram with you and make sure you always use the proper terms when referring to the different parts of a microscope.
What are the 12 parts of a microscope?

- Eyepiece Tube or Body Tube. The tube hold the eyepiece.
- Nosepiece.
- Objective Lenses.
- Arm.
- Stage.
- Stage Clips.
- Diaphragm (sometimes called the Iris)
Which part of the microscope focuses the light through the microscope?
Condenser Lens
Condenser Lens – This lens system is located immediately under the stage and focuses the light on the specimen.
What is the function of a compound light 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 is the function of the stage clips?
Stage clips hold the slides in place. Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power.

What is an organelle quizlet?
organelle. a tiny cell structure that carries out a specific function within a cell. nucleus. the control center of the cell that directs the cell’s activities; it contains the chemical instructions that direct all the cell’s activities (DNA)
Are structures that perform the daily functions of the cell quizlet?
An organelle is a membrane-bound structure in the cell that performs a specific function. Aerobic respiration is the breakdown of simple food molecules like glucose in the presence of oxygen. Chlorophyll-containing plastid found within the cells of plants and other photosynthetic eukaryotes.
