Abstract: A light-tight and collapsible chamber (120, 300) for use in demonstrating the optical performance of a piece of retroreflective sheeting placed within the chamber (120, 300) is provided. The chamber (120, 300) comprises a generally opaque polygonal back panel (130, 320) having a plurality of edges; a plurality of generally opaque side panels (140, 170) wherein adjacent side panels (140, 170) are attached to one another to form a light-tight connection and each of the plurality of opaque side panels (140, 170) are attached along and positioned essentially perpendicular to one of the plurality of edges of the back panel (130, 320) to form a light-tight connection; and an open area (150, 330) essentially parallel to and distanced from the back panel (130, 320) and forming an observation window permitting an observer to view the piece of retroreflective sheeting positioned within the chamber (120, 300). In one embodiment, the chamber (120, 300) further comprises a leaflet (310) capable of attaching to the piece of retroreflective sheeting attached to the back panel (130, 320). In another embodiment, the chamber (120, 300) can be collapsed in various ways.
