300x Microscope
Microscope Field Of View?

If the diameter of the file dof view is 8mm under 30x and is 4 mm under 60x, what is the number under 300x?

Show me how you did it D:

Change in the Field-of-View (FOV)
Diameter is inversely proportional to change in the Magnification.

If 300x is ten times bigger than 30x, the FOV Diameter for 300x will be ten times smaller than the FOV diameter for 30x

8mm/10 = 0.8mm diameter for 300x
