Abstract

To ensure that the facets of a mirror drum are accurately located, each facet body is formed from a plastics resin cast against an optically flat surface and is formed with locating means accurately positioned in relation to the optically flat surface, the flat facet body surface being given a reflective coating. The assembly of the coated facet bodies on the drum is effected using the locating means formed on the facet bodies and co- operating locating means formed on a drum core or on discs defining the end of the drum. The plastics resin may be cast in a trough having the optically flat surface as a removable base or in a mould formed with an elongate channel providing an elongate open upper face over which the optically flat surface is placed. Metal reinforcing bars may be located in the cast resin body or may be bonded to the surface of the cast resin body. In Figure 5, the stems of T-section metal reinforcing bars serve as the locating means and seat in precision-cut channels in the drum core. <IMAGE>
