Question

You calculate the diameter of the field of view under a 4x objective to be 5 mm. What is the diameter of the field of view under a 40x objective?

0.02 mm

4 mm

0.5 mm

2 mm

0.2 mm

Answer 1

Answer #1

To calculate the Field of View Diameter under high power the formula mentioned below can be used.

Diameter (under Low Power) X Magnification of Low power objective

Magnification of High Power objective

Substituting from the above question we get : 5 mm x 4X = 2O = 0.5 mm

40X 40
