Weboptical axis is the axis passing through the two centers of curvature of the optical surfaces. The mechanical axis passes through the physical center of the lens in a direction parallel … 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. If we give a in centimeters we can
