Supports the microscope.
|
Base
|
|
|
Vertical part of the microscope. To transport, you hold onto the base and the arm of the microscope.
|
Arm
|
|
|
The platform the slide sits on.
|
Stage
|
|
|
Holds the slide in position so the slide can be moved side to side and up and back.
|
Mechanical stage apparatus
|
|
|
Knobs that move the mechanical stage apparatus. One knob typically sits on top of the other. One knob moves the slide left and right and the other knob moves the slide front and back.
|
Mechanical stage knobs
|
|
|
Located under the stage. Is is used to adjust the amount of light passing through the object. Some microscopes also have an adjustable light switch that will also alter the amount of light.
|
Iris diaphragm lever
|
|
|
The larger of the two knobs located on both sides of the arm. It moves the low-power objective rapidly to focus the object. It is used only with the low-power objective.
|
Coarse focus knob
|
|
|
The smaller of the two knobs located on both sides of the arm. It is used for precise movements of the objectives to obtain the best focus possible.
|
Fine focus knob
|
|
|
Holds the objectives in position and rotates to move an objective into the vertical position.
|
Revolving nose-piece
|
|
|
The eyepiece you look through while using the microscope. It typically consists of a power of 10.
|
Ocular
|
|
|
A set of lenses known as: scanner (4), low-power objective (10), high-power objective (40), and oil immersion objective (100).
|
Objectives
|
|
|
The 4x/5x lens power of the microscope. (Red)
|
Scanning (scanner) objective
|
|
|
The 10x lens power of the microscope. (Yellow)
|
Low Power Objective
|
|
|
The 40x lens power of the microscope. (Blue)
|
High Power Objective
|
|
|
The 100x lens power of the microscope. (White)
|
Oil Emersion
|
|
|
If the ocular lens mag is 10 and the objective lens mag is 100, what is the total magnification?
|
1,000x
|
|
|
Your field of view ________ , as you increase power.
|
Decreases
|
|
|
Your field of view ________ , as you decrease power.
|
Increases
|
|
|
Your focal distance ________ , as you increase power.
|
Decreases
|
|
|
Your focal distance ________ , as you decrease power.
|
Increases
|
|
|
Which focal distance has the least amount of distance between the objective lens and the stage/slide, when using the 4x/5x or 40x?
|
40x objective use would give you the least amount of distance between the objective lens and the stage/slide.
|
|
|
What does Parfocal mean?
|
Parfocal is the experience of going from one objective lens to the next while the image remains in focus.
