1/4-scale model of the UV scanning polychromator spectroheliometer, S055
Quarter-scale model of the S-055 Ultraviolet Scanning Polychromator and Spectroheliometer used on Skylab's Apollo Telescope Mount (ATM). Model is constructed out of wood, aluminum, plastic, steel screws, and thin gauge wiring, and is mounted in a plexiglass and varnished pine case.
The object is rectangular with a long trapezoidal cover. The cover and one side of the object are divided into four rectangular heat panels bolted on. A series of wires on one side connects to a series of black boxes bolted onto the same side. Two wires are inserted into each connection, each of which is like a telephone jack.
On one side of the instrument is a a square aperture. Opposite the aperture is a parabolic mirror that is adjustable on horizontal and vertical axes. At the midpoint of the instrument is a heat rejection mirror that reflects unnecessary light back through the aperture. Another heat rejection mirror is positioned near the aperture. Beneath the aperture is a spectrometer that is positioned at the focal point of the mirror to catch the light from the mirror. The actual spectrometer is in the collection, object 2001-1-0018.
