Base: The bottom of the microscope, used for support Illuminator: A steady light source (110 volts) used in place of a mirror.
What is the function of the fine base on a microscope?
Focus (fine), Use the fine focus knob to sharpen the focus quality of the image after it has been brought into focus with the coarse focus knob. Illuminator, There is an illuminator built into the base of most microscopes.
What is base and arm in microscope?
Base – It acts as microscopes support. It also carries microscopic illuminators. Arms – This is the part connecting the base and to the head and the eyepiece tube to the base of the microscope. It gives support to the head of the microscope and it is also used when carrying the microscope.
Where is the base located on the microscope?
Base: The bottom of the microscope, used for support. Illuminator: A steady light source (110 volts) used in place of a mirror.

Where is the illuminator on a microscope?
base
Illuminator is the light source for a microscope, typically located in the base of the microscope. Most light microscopes use low voltage, halogen bulbs with continuous variable lighting control located within the base.
What does a mirror do on a microscope?
Plane or concave mirror, placed on the microscope base and used to send light onto the specimen and into the microscope optics. The mirror is mounted on a swiveling support, adjusted to reflect natural light or light from an artificial source in the desired direction.
Where is the ocular lens on a microscope?
While an objective is on the side of the observed object, the ocular lens (also called ocular or eyepiece, sometimes loupe) is on the side of the observing eye. It may contain a single optical lens or some combination of lenses and is normally placed in a cylindrical housing (barrel).
Where is the diaphragm on a microscope?
The diaphragm can be found near the bottom of the microscope, above the light source and the condenser, and below the specimen stage. This can be controlled through a mechanical lever, or with a dial fitted on the diaphragm.
What are the three main parts of the microscope and its function?
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 revolving nosepiece in microscope?
The revolving nosepiece is the inclined, circular metal plate to which the objective lenses, usually four, are attached. The objective lenses usually provide 4x, 10x, 40x and 100x magnification. The final magnification is the product of the magnification of the ocular and objective lenses.
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.
What are the 12 parts of a microscope?
Function of each Microscope Part
- Eyepiece or Ocular Lens. Eyepiece lens magnifies the image of the specimen.
- Eyepiece Tube or Body Tube. The tube hold the eyepiece.
- Nosepiece.
- Objective Lenses.
- Arm.
- Stage.
- Stage Clips.
- Diaphragm (sometimes called the Iris)
What are the basic points to remember on how do you use a microscope?
NOTES:
- Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.
- Always keep your microscope covered when not in use.
- Always carry a microscope with both hands. Grasp the arm with one hand and place the other hand under the base for support.

What is the iris diaphragm on a microscope?
Medical Definition of iris diaphragm
: an adjustable diaphragm of thin opaque plates that can be turned by a ring so as to change the diameter of a central opening usually to regulate the aperture of a lens (as in a microscope)
What is a microscope arm?
Arm – The arm of the microscope supports the body tube. Body Tube – The body tube is a hollow tube through which light travels from the objective to the ocular.Coarse Adjustment Knob- The coarse adjustment knob located on the arm of the microscope moves the stage up and down to bring the specimen into focus.
What are the 3 lenses on a microscope?
Compound microscopes use three lenses are used to accomplish the viewing, the eyepiece lens, condenser lens and objective lens. There can also be compound and electron lenses and these lend themselves to the power and magnification of the device itself.
How many ocular lenses does a microscope have?
An ocular lens consists of one to three lenses and is also provided with a mechanism, called a field stop, that removes unnecessary reflected light and aberration. Different types are available according to the magnification they provide, such as 7x and 15x.
Where is the nosepiece on a microscope?
A microscope user will find the revolving nosepiece between the ocular lens (the eyepiece) and the stage (where the microscope holds slides and other objects for viewing). On most models, the revolving nosepiece attaches to the lower portion of the microscope’s arm.
Where is condenser on microscope?
On upright microscopes, the condenser is located beneath the stage and serves to gather wavefronts from the microscope light source and concentrate them into a cone of light that illuminates the specimen with uniform intensity over the entire viewfield.
