The field of view is inversely proportional to the magnification of the objective lens. For example, if the diameter of your field of view is 1.78 millimeters under 10X magnification, a 40X objective will be one-fourth as wide, or about 0.45 millimeters.
WebA compound light microscope often contains four objective lenses: the scanning lens (4X), the low‐power lens (10X), the high‐power lens (40 X), and the oil‐immersion lens (100 X). With an ocular lens that magnifies 10 times, the total magnifications possible will be 40 X with the scanning lens, 100 X with the low‐power lens, 400 X with the high‐power lens, … WebNov 22, 2024 · Introduction: A microscope is an instrument that magnifies an object so that it may be seen by the observer.
