Abstract
A fiber optic probe is provided with a distal sampling end, a proximal end, and light delivery and collection paths therethrough. The probe includes a window disposed at the distal sampling end of the fiber optic probe, the window having a distal end and a proximal end. A lens is disposed near the proximal end of the window, the lens having a distal end, a proximal end, and an aperture. A light delivery optical fiber is provided having a distal end and a proximal end, the light rays being directed through the aperture. A collection optical fiber is provided in optical communication with the lens and the window. The probe may include a lens collection filter disposed between the window and the lens and an optical isolator provided within the aperture to optically isolate the light delivery path and the light collection path.
