    "abstract": "We present methods and results of the testing of an inexpensive home-made\ndiffraction limited lens system, the design of which was proposed in a recent\npaper and which has since been used (with slight alterations) by several\nresearch groups. Our system will be used for both: focussing a collimated laser\nbeam at a wavelength of lambda=830 nm down to a narrow spot and for collimating\nfluorescence light (lambda=780 nm) emitted from rubidium atoms captured in this\nspot. Useful tests for lens systems include the use of ray tracing software,\nshear-wave interferometers, the imaging of test charts and of polystyrene beads\nof a very small size. We present these methods and show how conclusions can be\ndrawn for the design under test.",
