description The invention relates to a raman optical fiber probe, and in particular to an ultraviolet raman optical fiber probe based on an optical fiber technique. Excited light is collimated through an ultraviolet parabolic mirror, a raman background signal of an optical fiber is eliminated through a Laser Line Filter, and the excited light is introduced into a focusing objective through a small ultraviolet reflecting mirror which is positioned inside the probe in front of the filter and coaxial with an optical principal axis, so that raman signal interference caused by the situation that laser directly radiates an Edge Filter or Notch Filter is effectively avoided, and the problems that a conventional optical fiber raman probe is low in light transmittance in an ultraviolet area and raman scattering signals of an optical fiber self and a filter can be easily caused are overcome. In addition, due to introduction of the optical fiber, flexible structure connection of probes with various spectrographs is achieved, and th
