DES after FRAUNHOFER,Joseph,von. circa 1814 Utzschneider Optical Institut, Benediktbeuern, Bavaria, Germany. DES WOLLASTON,William,Hyde,Doctor. 1802 London, England. This early Browning student spectroscope, or goniometer, has an optical train comprised of a collimator slit which allows light from a suitable source to pass through a telescope which focusses the light onto a prism mounted on the central axis of the instrument. The light is dispersed by the prism and is viewed by the observer through a second telescope which is on a graduated scale with a vernier so that the angle of refraction can be accurately measured. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
