WebSep 12, 2024 · The purpose of a microscope is to create magnified images of small objects, and both lenses contribute to the final magnification. Also, the final enlarged image is produced sufficiently far from the observer to be easily viewed, since the eye cannot focus on objects or images that are too close (i.e., closer than the near point of the eye). WebMagnification and working distance are properties of microscopes that have competing factors that must be balanced to produce an image with optimal detail and resolution. Working distance is the distance between the specimen and the objective lens; magnification is a function of the lens systems.
