The use of a commercially available filtered fiber‐optic Raman probe is discussed for the in situ identification of illicit drugs. This probe is also shown to be useful for remote Raman measurements in a collimated beam geometry. Fiber‐optic Raman imaging is discussed using single small‐diameter image guides and also image guides with attached imaging GRIN lenses. Finally, a demonstration of remote Raman imaging is presented using a simple modification of the same commercially available Raman probe that was used for illicit drug measurements.
