WebApr 1, 2024 · The diameter of the field of view of a typical compound microscope that uses a low power objective at 10x magnification is approximately 2 millimeters, or 2,000 micrometers. One millimeter is roughly equivalent to 1/25th of an inch, and 1 mm is 1/25,000th of an inch. Microscopes are optical devices used to view and magnify objects … WebWhen using fixed focal length lenses, there are three ways to change the FOV of the system (camera and lens). The first and often easiest option is to change the WD from the lens to the object; moving the lens farther away from the object plane increases the FOV. The second option is to swap out the lens with one of a different focal length.
