An incident ray hits the lens parallel to optical axis emerges :
Optical axis
without deviation
optical center
within the direction of light
Parallel to optical axis
passing through F'
emerges rays of light
Image focus point
F' is called
Optical axis
without deviation
optical center
within the direction of light
Parallel to optical axis
passing through F'
emerges rays of light
Image focus point
Lenses always
