Bio: Compound Light Microscope

Light source

Diaphragm

controls the amount of light reaching the specimen

Stage

the flat platform where the specimen slide is placed for observation, allowing the user to securely hold and position the sample while viewing it under the microscope

Stage clips

securely hold the microscope slide in place on the stage, ensuring it remains steady while being observed under the lens

Objective lens

capturing light reflected or emitted from a specimen, then focusing it to create a magnified, real image that is further magnified by the eyepiece lens, allowing for detailed examination of small structures

Revolving nosepiece

hold multiple objective lenses of different magnifications, allowing the user to easily switch between them by rotating the nosepiece to select the desired magnification level

Ocular lens

also called the eyepiece, on a compound light microscope functions to further magnify the image produced by the objective lens, essentially allowing the viewer to see the final, enlarged image of the specimen

Fine adjustment knob

to make small, precise adjustments to the focus of the image, allowing for a sharp and detailed view of the specimen, particularly when using higher magnification lenses; essentially, it "fine-tunes"

Coarse adjustment knob

to quickly move the stage up and down, allowing for a rough focusing of the specimen
