Abstract
We study the effect of the cosmological constant on the statistical properties of gravitational lensing. It is shown that the cosmological constant, if it dominates over the mass density, increases the lensing optical depth greatly, and its effect is much larger than the uncertainty arising different choice of the distance formula and statistical formulations. A realistic prediction is made for the lensing frequency talking account of various selection effects for two quasar samples and a constraint on Λ is obtained.
