Parfocal |
When the image is in sharp focus on any objective lens you can switch to any other objective lens without moving the stage at all and the image should still be in good focus |
|
|
Parcenter |
When an image is in the center field of view on any objective lens it will remain in the center when you switch to any other objective lens |
|
|
The two main functions of microscope |
Magnification & resolution |
|
|
Total magnification |
Multiplying the magnification of the objective lens that is in position by the magnification given by the ocular lens |
|
|
Course adjustment knob |
Regulates the position of the stage and the specimen relative to that of the objective lenses serving to bring the specimen closer to or farther from the objective lens |
|
|
Fine adjustment knob |
Used for precise focusing once the object has already been brought into focus using the course objective lenses |
|
|
Iris diaphragm |
Serves to regulate the amount of light that can enter the condenser which directs light through specimen |
|
|
Objective lenses |
Located above mechanical stage magnify the image of the object being viewed |
|
|
Brightfield microscope |
Microscope used in the class it's a microscope that allows light rays to pass directly from the light source through various other components of the microscope |
|
|
Illumination source |
Provides the light for viewing specimens on microscope |
|
|
Resolving power |
Depends on the design of the condenser the quality of the lenses the wavelength of light that is being used |
