  We present here a calculation of the configuration averaged optical
conductivity of random binary alloys CuAu and AgAu. Our formulation is based on
the augmented space formalism proposed by Mookerjee [J. Phys. C : Solid State
Phys. {\bf 6} 1340 (1973)] and the optical conductivity is obtained directly
through a recursive procedure suggested by Viswanath and M\"uller ["The user
friendly recursion method", Troisieme Cycle de la Physique, en Suisse Romande
(1993)].
