Table 1: The calculated optical depth as a function of redshift fordifferent values of $\Omega _{\rm L}$ and $\Omega _0=0.3$ .
Table 2: The calculated optical depths ( $\tau _{\rm GL}$ and $\tau ^p_{\rm L}$ for 3 gravitational lensed objects). The used parameters are: $\Omega _0=0.3,\ \Omega _{\rm L}=0.05$ , F=0.15. $\tau _{\rm GL}$ is the optical depth for macrolensing for quasars located at the same redshifts as the gravitational lensed objects.
