    "abstract": "We demonstrate the combination of a hemispherical solid immersion lens with a\nmicro-photoluminescence setup. Two advantages introduced by the SIL, an\nimproved resolution of 0.4 times the wavelength in vacuum and a 5 times\nenhancement of the collection efficiency, make it an ideal system for spatially\nresolved spectroscopy applications. The influence of the air gap between the\nSIL and the sample surface is investigated in detail. We confirm the tolerance\nof the set--up to an air gap of several micrometers. Such a system is proven to\nbe ideal system in the studies of exciton transport and polarization dependent\nsingle quantum dot spectroscopy.",
