Magnification Flashcards
1
Q
Total Magnification
A
Multiply ocular x objective
2
Q

A
Ocular 10 X Objective 4x = 40x
3
Q

A
Ocular 10 X Objective 40x = 400x
5
Q
Total Magnification – Oil Immersion
A
Ocular 10 X Objective 100x = 1000x
6
Q
Numerical Apertures
A
Scanning = 0.1; Low = 0.25; High dry = 0.65; Oil = 1.25
7
Q
Formula x Resolving Power
A
Lambda / 2x NA (numerical apertures) – Our microscope for example would be Scanning: 0.45/2(0.1) = 2.25
