Slide 15 - Diapositive

Slide 16 - Vidéo

The microscope

eyepiece lens = lens, magnifies 10x
tube = holds the eyepiece lens
revolver = holds the objective lenses, turns around
objective lenses = lenses hold by the revolver. Magnify 4x, 10x and 40x
stage = holds the slide
arm = used to hold the microscope when carrying
focus knob = lets you move the stage up and down. This helps you focus the image. There is a coarse and a fine knob. 
lamp = source of light
condensor = lets you control the amount of light passing through the slide
base = this is the base the microscope stands on
