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 at 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 distal end being received by the lens aperture. An optical isolator provided within the lens aperture to optically isolate the light delivery path and the light collection path. A collection optical fiber is provided in optical communication with the fiber collection filter. The probe may include a lens collection filter disposed between the window and the lens.
