  We present new results on the continuum extrapolation of the vector current
correlation function in the deconfined phase for three temperatures close to
the critical temperature utilizing quenched clover improved Wilson fermions and
light quark masses. A systematic analysis on multiple lattice spacing allows to
perform the continuum limit of the correlation function and to extract spectral
properties in the continuum limit. These results provide constraints for the
electrical conductivity and the thermal dilepton rates in the quark gluon
plasma for the given temperature range. In addition results on the continuum
extrapolation at finite momenta related to thermal photon rates are presented.
