Ocular Lens

Eyepiece of a microscope; 10x magnification (meaning you will 10x the objective lens)

Arm

Used to support the microscope when carried

rotating (revolving) nosepiece

contains objective lenses, allowing for changing of lenses for variable magnification of slide image

objective lenses

Primary lenses that magnify the specimen, 4x (red stripe/short) 10x (yellow stripe) 40x (blue stripe) 100X (longest lens)

stage

Supports the slide being viewed, is moved up and down in order to focus

stage clips

Holds the slide in place

mechanical stage control

adjust in order to move the slide around the(front,back,left,right) stage to see the different sections of the slide.

fine focus adjustment knob

this part moves the stage slightly to help you sharpen or "fine" tune your view of the specimen

coarse focus adjustment knob

this part moves the stage up and down to help you get the specimen into view

Light Control

controls intensity of light

Condenser

focuses light through the specimen

Iris Diaphragm Lever

regulates the amount of light passing through the condenser

Proper microscope storage

1. turn off light 2. lower stage 3. remove slide 4. put to lowest objective 5. wrap cord on back of scope, 6. cover with bag 7. store
