Abstract
A system useful for in vivo and ex vivo spectroscopy comprises a water source connected to supply water through a passage to an outlet at a flow rate sufficient to issue a laminar water jet from the outlet, a light source operative to emit a light beam that is guided to a sample by the water jet, and an analysis unit connected to receive collected light that has been emitted from the sample into the water jet and operable to analyze the collected light. Some embodiments provide endoscopes with integrated light guides.

A system useful for in vivo and ex vivo spectroscopy, the system comprising:
- a water source connected to supply water through a passage to an outlet at a flow rate sufficient to issue a laminar water jet from the outlet;
- a light source operative to emit light as a light beam that is guided to a sample by the water jet;
- an analysis unit connected to receive collected light that has been emitted from the sample into the water jet and operable to analyze the collected light.
A method for spectroscopy of a sample, the method comprising:
- delivering water from a water source through a passage to an outlet at a flow rate sufficient to issue a laminar water jet from the outlet;
- delivering a light beam from a light source into the water jet;
- directing collected light from the sample that has been collected and guided by the water jet to an analysis unit;
- and
- operating the analysis unit to analyze the collected light.
An endoscope comprising:
- an elongated casing having an instrument channel extending longitudinally along the casing to a distal end of the casing;
- and
- a light guide extending along the casing to the distal end of the casing in a lumen separate from the instrument channel, the light guide configured to receive light beam from a light source at a proximal end of the casing and to deliver collected light received by the light guide at the distal end of the casing to a proximal end of the light guide which is connectable to deliver the collected light to an analysis unit.
