principal focus
F is "behind the lens" on the
opposite side
of the lens as the incoming light
F is "in front of the lens" on the
same side
of the lens as the incoming light

rays
#1
top of the object, parallel to the axis, strikes the lens, refracts through F
#2
top of the object, passes through the center of the lens unbent
#3
top of the object, aims for F', strikes the lens, refracts parallel to the axis
#1
top of the object, parallel to the axis, strikes the lens, refracts through F (dot in line to F)
#2
top of the object, passes through the center of the lens unbent
#3
top of the object, aims for F', strikes the lens, refracts parallel to the axis (dot back refracted ray)
