We review the basic concepts of UV detectors and discuss why astronomers and planetary geologists place requirements of the detectors to be both UV sensitive and yet visible blind. This visible-blind requirement means that although CCD (and CMOS) based cameras can be quite efficient in the UV (approximately 40%), when filters are applied to knock out the necessary visible contribution, the effective CCD sensitivity is reduced significantly. We review several detector concepts from wide band-gap semi-conductors (primarily GaN-based) to Si-based (CCD and CMOS) and low temperature detectors (e.g., transmission edge sensors [TESs], superconducting Tunnel Junctions (STJs), and metallic magnetic calorimeters (MMCs). We conclude a new mission that would use a GaN photo-cathode camera for the UV low light level applications.
