Microscope Flashcards
Identify part and function
rheostat
alters the current applied to the lamp to control the intensity of the light produced
Identify part and function
ocular lens
magnifies the image
Identify part and function
arm
supports the body tube
Identify part and function
objective lens
gathers light from the specimen, magnifies the image of the specimen, and projects the magnified image into the body tube
Identify part and function
course focus knob
moves the stage up and down to bring the specimen into focus in a larger motion
Identify part and function
lamp
light source in your microscope
Identify part and function
Base
supports microscope
Identify structure and function
iris diaphragm control lever
regulates the amount of light passing through the condenser
light switch
turns light on and off
Identify part and function
mechanical stage control knobs
y axis
x axis
moves the slide across the stage in four directions for focusing
Identify part and function
mechanical stage
A flat mechanism that sits on top of the stage and allows the viewer to move a specimen small distances - a task that is otherwise difficult at higher magnifications.
Identify part and function
stage
The horizontal surface upon which the slide is placed is called the stage.
Identify part and function
substage condenser
This lens system is located immediately under the stage and focuses the light on the specimen
Identify part and function
fine focus knob
This knob is inside the coarse adjustment knob and is used to bring the specimen into sharp focus under low power and is used for all focusing when using high-power lenses.
Identify part and function
body tube
The body tube is a hollow tube through which light travels from the objective to the ocular.
Structure and function
revolving nosepiece
Several objective lenses of varying magnification and numerical
aperture are mounted on the revolving nosepiece. The nosepiece must click into place for the objective lens to be in proper alignment.
