  • Portable ultraviolet device for exploring mineral resource
    Patent number: 9000400
    Abstract: Provided is a portable ultraviolet device for exploring a mineral resource. The portable ultraviolet device for exploring the mineral resource may include a body, a visible component, an ultraviolet lamp assembly, and a darkroom component. The visible component is coupled to the body to pass through the body so that a mineral resource disposed at a lower portion of the body is observed from an upper side of the body. The ultraviolet lamp assembly part is coupled to the body to emit ultraviolet rays onto the mineral resource. The darkroom component is coupled to a bottom surface of the body to surround the visible component and the ultraviolet lamp assembly and defines an external light blocking space having an openable inlet in a lower portion of the body.
