FIELD OF VIEW = FIELD NUMBER / OBJECTIVE LENS MAGNIFICATION
What is The Field Number?
This is the second number on your eyepieces. For example, an eyepiece with WF10X/22 written on it has a field number of 22.
EXAMPLE 1: If you're using a compound microscope:
If your eyepieces have written on them: WF10X/20
And you're using the 40x objective lens.
You will have a field of view of:
20 / 40 = 0.5mm (500 microns)
EXAMPLE 2: If you're using a stereo / dissecting microscope:
If your eyepieces have written on them: WF10X/22
And you're using the 0.7x zoom increment.
You will have a field of view of:
22 / 0.7 = 31.42mm
