The present disclosure, according to one embodiment, relates to an optical device for direct visualization, imaging, and spectroscopic measurements of tissue abnormalities at various anatomical sites. Such sites include, but are not limited to, the oral cavity, the cervix, and the skin. In one embodiment, the device comprises: a frame; at least one light-emitting diode light source mounted on the frame for illuminating a tissue, wherein the at least one light-emitting diode light source is chosen from a fluorescent light source, a polarized white light source, and an unpolarized white light source; at least one loupe mounted on the frame for visually observing the tissue; at least one filter disposed between the tissue and the loupe for filtering light reflected from the tissue; and an energy source operably connected to the at least one light-emitting diode light source. |
