Optics basics
1
Q
F = primary focal point
A
object location for image at infinity
2
Q
F’ = secondary focal point
A
image location for object at infinity
3
Q
f = primary focal length
A
object distance for image at infinity
4
Q
f’ = secondary focal length
A
image distance for object at infinity
5
Q
italic L (eq)
A
italic L = n / italic l
6
Q
n = index of refraction through media (m)
A
n = c / v(m)
7
Q
italic l (def)
A
object distance
8
Q
italic l’ (def)
A
image distance
9
Q
italic F (def)
A
lens power
10
Q
italic L (def)
A
object vergence
11
Q
italic L’
A
image vergence
12
Q
Vergence relationship equation
A
italic L + italic F = italic L’
object vergence + lens power = image vergence
