SmallSats have become powerful platforms from which to conduct leading scientific investigations with cutting-edge technology developments at low cost with rapid turn-arounds. Wolter-I X-ray telescopes with a focal length of < 1.5 m use VOXI optics to enable a wide range of missions with broad science applications for scientific research over multiple disciplines. We will describe the development and potential of these optics, and a few of the applications for VOXI optics considered to date.
