Resumen:
We present explicit expressions for optical scalar and deflection angle for weak gravitational lensing at second order in the perturbation of flat spacetimes by using the spin-coefficient method. We give explicit expressions for convergence, shear and rotation and compare them with some of the expressions found in the literature.
