We describe a robust and reliable fluorescence detector for single atoms
that is fully integrated into an atom chip. The detector allows spectrally and
spatially selective detection of atoms, reaching a single atom detection efficiency
of 66 %. It consists of a tapered lensed single-mode fiber for precise delivery of
excitation light and a multi-mode fiber to collect the fluorescence. The fibers are
