The identification and characterisation of radioactive material and other hazardous substances are essential requirements for the nuclear industry. Raman spectroscopy can be used to identify substances; however, given the challenging nature of the environment, instruments typically cannot be located within 1 m of the target substance. A new stand‐off Raman instrument using a spatial heterodyne spectrometer mounted on a remotely operated vehicle (ROV) is presented, and its ability to identify a range of chemicals of interest to the industry is demonstrated within a representative environment. The instrument demonstrated an ability to routinely make Raman observations at 1 m from the target with all sensitive electronic elements situated remotely outside the target environment.
