    "abstract": "We present the design of a diffraction limited, long working distance\nmonochromatic objective lens for efficient light collection. Consisting of four\nspherical lenses, it has a numerical aperture of 0.29, an effective focal\nlength of 36 mm and a working distance of 36.5 mm. This inexpensive system\nallows us to detect 8*10^4 fluorescence photons per second from a single cesium\natom stored in a magneto-optical trap.",
