What's the difference between eyepiece and microscope?

Eyepiece


Definition:

  • (n.) The lens, or combination of lenses, at the eye end of a telescope or other optical instrument, through which the image formed by the mirror or object glass is viewed.

Microscope


Definition:

  • (n.) An optical instrument, consisting of a lens, or combination of lenses, for making an enlarged image of an object which is too minute to be viewed by the naked eye.

Example Sentences:
