Moving lenses stereoscope

Dating

1868 - 1874

The instrument allowed the three-dimensional vision of an object represented with two bi-dimensional images (Stereograms). The words "a lenti mobili" [with moving lenses] means that the instrument has a technical innovation: it has a device with which is possible to move in the same time the two lenses (like the modern binoculars).

The additional indications which integrate the items of the conservation's state have the following meaning: (?) = maybe complete; M = maintenance; P = partial; R = restored; D = used for teaching; NC = not checked; X = impossible to verify.

In order to avoid that instruments' cards without the english description text of the device be directly selected, I added a special filter with which only the complete cards are shown in the menu. Anyhow all the partial english instruments' cards (with instrument's dating, dimensions, state of conservation...) can always be seen even if they haven't the english description text. To read this uncomplete cards is sufficient to click, for example, on an instrument's picture or on the word "View" of the table column called "Card" every time they appear in the other pages of this database.
