We present a design concept that provides selectable band imaging in the optical and ultraviolet. The bandpass is created through reconstructive spectroscopy, utilizing crossed gratings, and creates an image, not a spectrum. The bandpass depends upon the field of view, the object location within that field, and the illuminated area of the second grating. All three factors are in principle selectable in real time, so that an instrument utilizing this technique is extremely flexible in its application. The technique utilizes no transmitting optics, and therefore is usable down to the limits of normal incidence reflectivity (～ 40 nm).
