PARTS OF THE MICROSCOPE
| A | B |
|---|---|
| STAGE | Part of the microscope that supports the slide that is being viewed. |
| COVER SLIP | Name for the small plastic or glass piece that is used to cover a water drop on a slide. |
| SLIDE | Small glass plate on which specimen are placed for viewing. |
| POWER | Refers to the degree of magnification for a lens. |
What supports the slide being viewed?
Base: The bottom of the microscope, used for support Illuminator: A steady light source (110 volts) used in place of a mirror. Stage: The flat platform where you place your slides. Stage clips hold the slides in place.
What part of the microscope supports the slide being viewed?
Stage
Stage: The flat platform that supports the slides. Stage clips hold the slides in place.
Where do you place the slide to be viewed?
stage
Place a slide on the stage, label side up, with the coverslip centered. On LOW POWER ONLY, use the coarse focus knob to get the object into focus. If you cannot see anything, move the slide slightly while viewing and focusing.
Which part of the microscope helps you to look through?
eyepiece
Both of these microscopes have an objective lens, which is closer to the object, and an eyepiece, which is the lens you look through.
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.
Which part of the microscope holds and supports the specimen?
Stage – This is the section on which the specimen is placed for viewing. They have stage clips that hold the specimen slides in place. The most common stage is a mechanical stage, which allows the control of the slides by moving the slides using the mechanical knobs on the stage instead of moving it manually.
Where you look into the microscope this part allows you to view the image on the stage and contains the ocular lens?
EYEPIECE This part allows you to view the image on the stage and contains the ocular lens.
What part of the microscope supports the body tube *?
Arm
Arm – The arm of the microscope supports the body tube.
What part is used to tilt the microscope for more a comfortable viewing?
Inclination Joint: Where the microscope arm connects to the microscope base, there may be a pin. If so, you can place one hand on the base and with the other hand grab the arm and rotate it back. It will tilt your microscope back for more comfortable viewing.
What part of the microscope holds the slide firmly in place?
Stage
Stage: The platform where you place the microscope slide. It contains a slide holder, which is a spring-loaded clip that holds your slide firmly in place on the stage.
Why must the slide be kept in place?
It protects the microscope’s objective lens from contacting the specimen and vice versa; in oil immersion microscopy or water immersion microscopy the cover slip prevents contact between the immersion liquid and the specimen.
What holds the slide and moves up and down?
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. One moves it left and right, the other moves it up and down. Usually you will find 3 or 4 objective lenses on a microscope.
Which of the following provides support to the microscope?
The Microscope Base
The base provides stability and support for the microscope when it is upright. The base also typically holds the illuminator, or light source.
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.
What are the magnifying parts?
They have an objective lens (which sits close to the object) and an eyepiece lens (which sits closer to your eye). Both of these contribute to the magnification of the object. The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x.
What parts of the microscope are being connected by the inclination joint?
The inclination joint of a microscope is located at the bottom of the instrument, where the base connects to the arm. The inclination joint allows a microscope to tilt. To suit taller or shorter people.
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 part of the microscope holds the ocular lens?
PARTS OF THE MICROSCOPE
| A | B |
|---|---|
| EYEPIECE | This part allows you to view the image on the stage and contains the ocular lens. |
| NOSEPIECE | This part holds the objective lenses and is able to rotate to change magnification. |
| OBJECTIVE LENSES | These are found on the nosepiece and range from low to high power. |
Which objective allows you to see the largest area of the object you are viewing?
Parts of the Microscope
| A | B |
|---|---|
| the actual area of the slide as seen through the microscope | field of view |
| objective that allows for the largest field of view | scanning |
| objective that allows for the smallest field of view | oil immersion |
| objective that requires the diaphragm to be opened more | high power or oil immersion |
What holds and turns the objectives into viewing position?
Arm Supports the body tube Revolving nosepiece Holds and turns the objectives into viewing position. Low-power objective Contains the lens with the lowest power magnification.
