We discuss the order parameter correlation function in the vicinity ofcontinuous phase transitions using a two-parameter scaling form G(k) = k_c^{-2}g(k\xi,k/k_c), where k is the wave-vector, \xi is the correlation length, andthe interaction-dependent non-universal momentum scale k_c remains finite atthe critical fixed point. The correlation function describes the entirecritical regime and captures the classical to critical crossover. One-parameterscaling is recovered only in the limit k/k_c->0. We present an approximatecalculation of g(x,y) for the Ising universality class using the functionalrenormalization group.
