It is made up of lens in which the diameter field of view can be determined.
The diameter of the viewed field in an optical microscope is termed the field number and represents the diameter of the field measured in millimeters (mm) at the intermediate image plane.
From the question, there are two types of field of view
- <u>Low-power field of view</u>: which is 2 millieters(mm) and
- <u>High power field of view</u>: which is 10 × low-power field of view
Therefore, to determine the diameter of the field of view when using high power is
10 × 2 = 20mm
