The first step is to locate the sample with a low-power objective and position the microscope slide so that the area of interest is squarely in the central portion of the stage opening. It is often desirable to rotate the immersion objective (without oil) into place to ensure the correct location of the specimen.

Move the high-power objective a little to one side and place a drop of oil on the slide, directly over the stage opening. While watching the oil-immersion objective, bring it carefully into ... After each use, remove the slide from the stage, wipe away the oil, and place the low-power objective in vertical position.

As we estimate the size of the cell that we are viewing we must take into consideration the objective that we are using to view the object with and the diameter of the field of view (FOV.) Using the scanning objective, the diameter of the FOV is 4.5 mm. The diameter of the FOV for low power is 1.8 mm, the diameter of...
