WebOne part of our exercise involves the direct measurement of the diameter of the field of view using a clear ruler at 40x and 100x. Because the working distance of the 40x objective is shorter than the thickness of that ruler, the diameter at 400x cannot be directly measured. To determine this value an equation is given in the manual that ... Web1.5 mm / 4 = 0.375 mm = 375 µ. Divide the high power magnification of your microscope by the low power magnification to determine how many times larger you lower power field is than your high power field. 400 / 100 = 4x. Now determine the diameter of your high power field by divinding the diameter of your microscope's low power field by 4.
