4. 4X 10X 40X 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. Depth of Field Not in focus In focus

5. Stage Micrometer Ocular Micrometer Stage Micrometer = 10 units =10*0.01mm =.1mm Ocular Micrometer = 9 units 1 ocular division =.1mm / 9 units = 0.011mm

6. Each small division = 0.011 mm This cell spans across 11 ocular divisions. How wide is this cell? 11*0.011=0.121mm.
