Depth of Field – the vertical distance of an object that is in focus. When magnification is increased, less of the object is in focus (depth of field decreases) – BUT greater detail of the area in focus can be seen.

Stage Micrometer
Ocular Micrometer
Stage Micrometer = 10 units =10*0.01mm = .1mm
Ocular Micrometer = 9 units
1 ocular division = .1mm / 9 units = 0.011mm
Each small division = 0.011 mm
This cell spans across 11 ocular divisions. How wide is this cell? 11*0.011=0.121mm.
