Question
Chapter 2, Problem 3TQ
Summary Introduction
To review:
The appearance of artifacts in microscopic images and the methodology to classify optical artifacts and an actual feature of an image.
Introduction:
The focusing of an object is the process by which the settings of the eyepiece are adjusted in order to get a clear image. The ability to concentrate the light rays and view a clear image depends upon how close or far the specimen is placed from the central point where the light rays converge. Any sort of interference while preparing the sample especially in high-resolution microscopes can affect the outcome.

There is no relationship. When magnification increases, depth of field decreases. When magnification increases, depth of field increases. Stereomicroscopes offer a lesser depth of field than compound microscopes. The depth of field of a microscope determines how much magnification it can achieve.arrow_forward
