Device and method for visualization of fluorophores

[0004]In accordance with one embodiment of the invention, a fluorophore visualization device is described for the naked eye visualization and / or imaging of fluorophores. The device includes a first chamber defined by a set of walls including a horizontally disposed top, a front wall, and a floor. The walls of the chamber are opaque. The top wall of the chamber has one or more openings for removably receiving one or more test tubes. The test tubes include fluorophore containing compositions, which emit light at longer wavelengths upon excitation by light at shorter wavelengths. The front wall of the chamber includes a first window positioned so that the test tubes can be observed through the window. A light source providing excitation light is positioned within the chamber. The excitation light excites the fluorophores, causing them to emit light, which can be seen through the window, thereby enabling the fluorophores to be observed by the naked eye. The light source is so positioned
