How does a color changes works in glass, glass segments or a polymer material?
This consists usually of a small, geared motor with a disc. It can be made of glass, a polymer material or glass segments in a number of colors. The motor causes the disc to revolve within from of the common end, changing the color of the issuing light. Lower priced systems use glass whilst or colored films most others make use of dychroic filters. Within animation illuminators in place of a disc, there is a turning drum of glass or polycarbonate along with color films or varnishes applied in particular patterns to create movement and rapid color changes.
