Abstract
In this paper, we investigate the focal surfaces obtained by thetimelike normal rectilinear congruence whose straight lines are normal to spacelike surface, in the Minkowski 3-Space. Then, the relation n 1KZ1 + 2KZ2 = 0 between Gaussian curvatures of these focal surfaces are examined and finally the relation which concern with area preserving correspondence between the focal surfaces are given.
