Fig. 9.8 Variation of the coefficients of the reduced flexure z/aq = A2P2 + A4P4 + Â6p6, from (9.45), of single lenses of same central thickness T0 = t0/a = 0.06 in function of the pseudopower W. Material: Fused Silica E = 7.90 x 105 kgf/cm2, v = 0.165. Maximum radial stress at center: ar (0). Load q in kgf/cm2
