Question

3. What is the diameter of the field of view (DFV) of a 1000x objective lens if the DFV of a 400x objective lens is 500 μ? Express your answer in mm.

Answer 1

Answer and Explanation:

If an objective lens of 400x has a DFV of 500цm

then what would be the DFV of 1000x=?

1000*500/400

=1250цm

1mm=1000цm

? = 1250цm

1250*1/1000

=1.25mm
