Accession Number: 2012.psy.104.a-b
Component A: The instrument is mounted on a three-legged iron stand 18 cm tall. The instrument consists of a central cylinder in which several prisms would have been housed. Two 26 cm tubular arms with optical components radiate from the central cylinder horizontally. Another shorter optical component, 7 cm long, is also attached to the cylinder. A large cylindrical weight on a steel rod extends from the base of the central cylinder.
Component B: A small box containing three broken prisms from the spectroscope.
Primary Materials: Iron, brass, glass
The lid is engraved “Franz Schmidt & Haensch, Berlin, Germany.”
Dimensions (cm): Height = 33, Width = 30, Length = 59
Used to measure the properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials
Good. Slight amounts of corrosion. Tape gum on one leg. Masking tape attached to lid.
