In our set-up half of the paraboloid mirror covers a solid angle of $\\pi$ corresponding to a numerical aperture of N.A.\\,$\\approx 0.85$. The optical system can be used for far- and near-field spectroscopy. In the far field the polarizations can be maintained to within 80-90\\%. In combination with a scanning microscope (AFM/STM), tunneling or near-field experiments are possible with less than 10\\% loss of aperture.
