ow /u. Such a combination is also formedby the contact of a double Cc. lens of, say, ^=1-5 with a double Cx. lens of,say, /x=l-6, the two being of equal curvature. The focal power can be foundby calculating for each lens separately and then adding them together, orby calculating for each surface… … Fig. 206. and two nodal points in the system such that the distance P1Nl=P2N2=i\- Fv and Fx/ F2=ju1/fi3. The cardinal points are calculated from thefollowing formulae. F, Wlr2 1 i\(fi2 -/u3)+r2({A2 -fa) - t(/u2 -fa) {/u2 -ju3)/jh2Let the denominator of the above be called Q, then: *r A^lTl*2 Q F2=…
