1

What is the formula to find the diameter of, per say, field B?

Diameter of Field B= (Diameter of Field A x Total Magnification of field A)/Total Magnification of field B

2

What are the estimated field diameters for the scanning (4x), low power (10x), high power (40x), and oil immersion (100x) objective lenses in mm?

Scanning (4x): 4.5 mm

Low power (10x): 1.8 mm

High power (40x): 0.45 mm

Oil immersion (100x): 0.18 mm
