Microscopes 101

A microscope is an instrument widely to magnify and resolve the image of an object that is otherwise invisible to naked eye. For resolving the details of objects, which otherwise cannot be achieved by naked eye, a microscope is used. This test will help the student to identify the different parts and function of the microscope.
STUDY
PLAY
Arm
Supports the tube (& eyepiece) and connects the tube to the base
Eyepiece
the lens at the top that you look through. Magnification of 10X on our microscopes
Base
The bottom of the microscope, used for support
Body tube/ Eyepiece Tube
Connects the eyepiece to the nosepiece & objective lenses
Coarse adjustment
Used for focusing on the lowest power objective lens ONLY (red)
Fine adjustment
Small Knob, moves the stage slightly to bring slide into focus
Objective lens
Three lenses found on the nosepiece. (10X, 40X, 100X powers)
Stage
The flat platform where you place your slides. Stage clips hold the slides in place here. By turning the course and fine adjustment knobs you can raise and lower this piece.
Stage clip
hold the slides in place.
Diaphragm
Located under the stage, controls the amount of light shown through the specimen
Total power of magnification
the total power calculated by multiplying the eyepiece lens power X the objective lens power
wet mount slide
prepared with water, and used to view moving microscopic organisms
cover slip
when making a wet mount slide, this part is dropped at a 45 degree angle onto the specimen
compound light microscope
has a light and is used to view cells and moving organisms, 2D image
microscope clean up
Microscope should be returned to its starting "position"- on lowest power objective lens (Red Band), stage lowered all the way down, light switch off, slide and cover slip cleaned
red band objective lens
lowest power objective lens, 4x
pipette
measures and holds liquid, can dispense one drop at a time
