Question
Chapter 4, Problem 2.2A
Summary Introduction
To write:
The diameter of the scanning field of view in millilmeters.
Introduction:
Magnification can be defined as the process of intensifying not physical size but the visible size, of something. This amplification is quantified by a calculated number. When this value is less than one then it is known as a reduction in size. It is known as the de-magnification or minification.

Students have asked these similar questions
What is the total magnification of 4x objective lens and diameter of field of view in micrometers?
Using the Field of View (FoV) formula:
(Low Magnification/High Magnification)= (High Field of View/Low Field of View)
determine the FoV in microns for all other objective lenses (4x,10x,40,100x) given that the diameter of the 4X scanner FoV is 3.2 mm
Please, explain with the formula how it was used and how values were added
which objective lens is in place if the object you are viewing is magnified 1000x? (assume ocular lens magnification = 10x)
