Objectives and eyepieces

  • R. Haynes


The image formed by a microscope is produced by the action of both the objective and the eyepiece. Of the two lenses, the objective is most important because it determines the detail that can be seen in the final image and the optimum useful magnification. It has three important characteristics; namely its magnifying power, its resolving power, i.e. its ability to separate fine detail in the image, and its ability to gather light from the object. The eyepiece enlarges the image formed by the objective to the optimum overall magnification and corrects residual aberrations in the primary image, but it cannot improve the detail in the image formed by the objective.
