Posted: 05 Apr 2011 05:12 PM PDT The Príncipe Felipe Science Museum has renewed its contents with the “Window on Valencia” exhibition located on Minor Street. Entry is open to all, with a display of two microscopes that form part of the collection belonging to the National Museum of Science and Technology (MUNCYT). One of the pieces on display is the first electronic microscope in Spain, which arrived in 1947. The appearance of the electronic microscope in the 1930s gave researchers the chance to study the smallest structures seen until then. The RCA transmission electronic microscope, measuring 0.64 x 1.05 x 1.90 meters, was installed in 1947 in the Spanish National Research Council’s Daza de Valdés Optical Institute. It is complete with all its original accessories and spare parts, and there is also a photographic archive of all the research work carried out with it. As for the Tesla BS 242 microscope, this measures 36 x 55 x 87 cm and was developed as of 1950 in Czechoslovakia. In 1958 it was awarded the gold medal in the Brussels Universal and International Exhibition. This instrument was acquired by the Jiménez Díaz Foundation in Madrid through a Czech engineer and with it the first electronic microscope study on internal cell structure was published in Spain, as well as numerous other research projects on pathological anatomy. It cost approximately 800,000 pesetas and was used until 1974. It was donated by the Jiménez Díaz Foundation to the National Museum of Science and Technology in 1992. |
