Optical axis deviation
Webfrom the optical axis. Rays converge to the secondary focal point. The ray bundle is rotated through an angle δ where δ=−a/f'=-aF. To get the prismatic deviation, remember that prism power ∆ is one hundred times the angle of deviation in radians so ∆=100δ=-100aF. This is the famous Prentice's Rule.
