Description: | Mounted monochrome photograph of Professor John Carroll's solar eclipse echelon spectrograph made for his eclipse expedition to Canada in August 1932 and taken to Omsk in Siberia in 1936. A 2-foot folding carpenter's rule in the photograph shows the scale. A side panel removed from the spectrometer allows the interior echelon (?) to be seen. Two slit units sit in front of the spectrometer in low wooden frames. The frame of photograph is in thin, black-painted wood with rear label "Frank Nicol./ 33 Broad Street, Aberdeen,/ Picture Framer and Photographer,/ Artists' materials./Gramophones and Records." Original string on rear. The original spectrometer, made in the Department of Natural Philosophy, does not survive. An account of the proposed eclipse exhibition to Canada is given in the Press and Journal of 15th July 1932 (including a picture of this instrument) and an account of the eclipse expedition to Omsk can be found in the Aberdeen University Review, November 1937. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1932 | Source: | University of Aberdeen | Identifier: | http://calms.abdn.ac.uk/Geology/dserve.e... | Go to resource |
