A device with a total reflection prism, used to obtain images without the effects due to the light dispersion, because the system is achromatic. -
It is a circular shaped lens, with a 67 mm diameter, protected by a case. This is a focus lens that, in an optical instrument, can improve quite satisfactorily the chromatic aberration. -
The device allows to study the laws of reflection and refraction of a beam of light; such laws are attributed to Willebrod Snell (Leida 1591-1626) and to Renè Descartes (La Haye-Turenna 1596-Stoccolma 1650). -
The device is also called “Colladon fountain”; this name is due to the Swiss professor of physics D. Colladon who, in 1841, during a lecture about hydraulics, casually caught a beam of light in a water jet; this put in evidence the phenomenon of internal reflection. -
It is a “physique amusant” instrument through which, rotating a pipe containing mirrors, it is possible to observe the formation of symmetric shapes of different colours. It was invented by David Brewster in 1817, and after a few months from its patent, a lot of specimens were built and sold both in London and in Paris. -
The device is made of a total reflection prism which allows to get a faithful image, for instance, of a landscape, of a monument, or of any subject. It was invented by Wollastone, who presented it with the name of “bright chamber” in 1806; later on G.B. Amici improved it. -
This device can give straight and magnified images of earthen objects. This telescope was bought second-hand in the London atelier of Dollond, one of the most well-known manufacturers of scientific instruments between the 18th and the 19th centuries. -
This device can be considered an improvement of the binoculars, because it allows a binocular vision. It is called that way because it was used for naturalistic observation. -
This device shows that white light is made by the basic colours of the solar spectrum. It was Newton who studied the dispersion of light. In 1672 he published his theory on the nature of colours on the review Philosophical Transactions of the London Royal Society. -
The device is used to measure the power of a light source, for example of a candle, if we know the one of another source, called sample source. The individual factor that determines such measure, which is due to the visual skills of the observer, can be reduced substituting the fat spot paper with a system of two prisms, as suggested by Lummer and Brodhun. -
A series of four coloured glass slabs mounted on cardboard of different dimensions and shapes. The colours of the slabs represent two couples of complementary colours: blue and yellow, green and red. The glass slabs were used to study the perception of colour or as accessories for experiments of optics. -
The conic lens is an optic disposal that causes, if dutifully hit by a beam of light, a rainbow as happens naturally, because of reflection, total reflection and dispersion, when solar light passes through raindrops. -
The device is made up by a converging lens. We can consider as prototypes of magnifying lenses the glass globules and bubbles full of water whose capacity to produce magnified images was already known in old ages. -
A sample of compound microscope which is used to magnify extremely small objects, that are often invisible with naked eyes or are, as we say, microscopic. -
A sample of compound microscope with a cardboard case. -
An example of simple microscope made up by a converging magnifying lens; it allows to observe small objects. -
Simple microscope mounted in bone and with pocket-size. -
A simple microscope of the kind used in the 18th century to observe insects and thus called “flea microscope”. -
The device, which is usually fixed at an open window, with its mirror facing the outside, allows to reflect the solar rays towards the inside of a place. It was used for optics tests and for the study of solar light. -
Two shutters for light-holder. -
It is a device made up by three small glass slabs with a brass structure. It is ready to contain some transparent matter whose microscopic details are magnified and projected on a wall by means of a solar microscope. -
Simple liquid-holder. -
It is a small glass slab on which a diffraction grating is engraved; this is characterized by parallel lines, equidistant, extremely near to one another; the number is 14510 for inch, model A. Rowland. The grating allows to study the phenomena of diffraction. -
A series of four tables showing interference figures, obtained as a result of phenomena associated with achromatic polarization of white light. -
This series, belonging to the Cabinet of Physics of the School, includes three kinds of lenses: one is biconvex, one is plane-convex, and one is biconcave. -
A series of triangular prisms which allow to show the phenomenon of the dispersion of white light, in particular the stationary prism is used for the recomposition of light. -
The device allows, because of the phenomenon of the dispersion of light, to show the influence of the medium on the different deviations undergone by a luminous ray falling on the surface of the four prisms of different materials and heights that make it up. -
The bottle is an example of hollow prism for liquids used to analyze the phenomenon of strong dispersion. Such a phenomenon is observed, for instance, filling a hollow prism with carbon disulphide. -
A series of two glass prisms, with isosceles triangular section, with a different opening angle, equipped with metal fittings on three faces. They were used for experiments in optics. The possibility to detour a white light ray without wasting it is an extremely important result in the study and building of lenses. -
The two mirrors, one convex and one concave, allow to study the building of the image, a study which has been greatly improved by the use of Gauss’ experimental conditions -
The device consists of a glass rectangular mirror, mounted on a metal fitting which also covers its surface. It was used in experiments of optics. -
The device is a metal cylindrical mirror. The series of six figures, that were used with the mirror itself in optics, are missing. -
This plane mirror is inserted on a brass cylindrical structure; it was used in experiments of optics. -
It is a metal spherical mirror whose use is limited to parts of the surface of the device itself. -
Only the Bunsen burner on a brass container is left of the original appliance owned by the Liceo. The burner is a spring thought of in such a way as to be able to study the spectra of gases of solid substances dipped into the flame. -
The instrument is used to study the spectrum of the different sources of light. The spectroscopic analysis has allowed to study the elements that build up the matter which is present not only on the earth but in the whole universe. -
This instrument allows a tridimensional vision of an image. It was invented by Charles Weatstone around 1830 and then improved by Davis Brewster in 1849. Since Brewster could not find opticians willing to produce such an instrument in England, he was able to show the first specimen only in 1851 thanks to a firm in Paris. Queen Victoria enjoyed this instrument and introduced it in her own drawing room, making it as popular as the kaleidoscope. -
Quite thick crystal chamber with a rectangular section. It can be used in several ways in didactic experiences of optics. -
The device is a glass container of semi-cylindrical shape; it was used to study the phenomena of reflection, refraction and total reflection. -
It is a crystal chamber used for the phenomenon of refraction between two liquids, according to Snell’s law.
