The parts of the microscope are as follows:
A = Eyepiece
It’s what you look through to see the specimen. It’s usually 10x or
B= Eyepiece tube
Connects both the objective lens and the eyepiece
Holds the objective lens in place or allows for the rotation of each lens.
D= Objective lens
Usually consist of 3-4 (4x, 10x, 40x, 100x oil immersion). These lenses magnify the image of the specimen.
E= Specimen stage
The moveable platform on which slides are mounted for viewing.
Located just beneath the stage and changes, controls, adjusts, or varies (decreases or increases) the amount of light passing through the condenser lens and ultimately what reaches the specimen. It can drastically affect the focus of the image.
