We explore the continuum limit a→ 0 of meson correlation functions at finite temperature. In detail we analyze finite volume and lattice cut-off effects in view of possible consequences for continuum physics. We perform calculations on quenched gauge configurations using the clover improved Wilson fermion action. We present and discuss simulations on isotropic Nσ3× 16 lattices with Nσ=32,48,64,128 and 1283 × Nτ lattices with Nτ=16,24,32,48 corresponding to lattice spacings in the range of 0.01 fm \lsim a \lsim 0.031 fm at T≃1.45Tc. Continuum limit extrapolations of vector meson and pseudo scalar correlators are performed and their large distance expansion in terms of thermal moments is introduced. We discuss consequences of this analysis for the calculation of the electrical conductivity of the QGP at this temperature.
