Objective Lens

  • The objective lens is the front lens, closest to the object being observed.
  • It collects light and creates the first magnified real image.
  • It determines most of the resolution, brightness, and image quality.
  • In microscopes, common objective magnifications are 4×, 10×, 40×, 100×.

Simple idea: The objective lens is the main lens that actually “sees” the object.

Eyepiece

  • The eyepiece is the lens near your eye.
  • It further magnifies the image produced by the objective lens.
  • Changing eyepieces changes the overall magnification.

Simple idea: The eyepiece makes the image big enough for your eye to see.

Total Magnification (Microscope)

Total Magnification = Objective Magnification × Eyepiece Magnification Example: 40× objective × 10× eyepiece = 400×
