Model of light path
Accession Number: 2011.ph.506
Instrument Name: Model of light path
A black T-shaped metal rod is set into a pyramidal base. Supported on each arm of the ‘T’ is a series of rods, lenses and prisms, in which the rods indicate the path of a beam of light through the prisms and lenses. At the tip of the rods is a conical arrow head, and at the other end a ‘fletching-like’ end consisting of repeated cones. The rods pass through the same arrangement of lenses and prisms: a large round lens, two right-angle triangle prisms, and two smaller round lenses.
Primary Materials: Metal, Glass, Plastic
On the base: “C.P. GOERZ BERLIN”
On a label attached to the model: “PHY124″ This refers to the object’s entry in the 1978 catalogue. On the reverse side of this label it reads: “BINOC. skeleton”.
Dimensions (cm): 18cm x 12cm x 14cm
