	We report on an ultra-low birefringence dodecagonal glass cell for ultra-high vacuum applications. The epoxy-bonded trapezoidal windows of the cell are made of SF57 glass, which exhibits a very low stress-induced birefringence. We characterize the birefringence &Delta;n of each window with the cell under vacuum conditions, obtaining values around 10<sup>-8</sup>. After baking the cell at 150 ºC, we reach a pressure below 10<sup>-10</sup> mbar. In addition, each window is antireflection coated on both sides, which is highly desirable for quantum optics experiments and precision measurements.</p>},
