Abstract
A projection television lens cell and system including a tubular optic support structure having an interior with a longitudinal central axis. A first annular support surface extends around the longitudinal central axis for receiving a first optic having an outer circumferential edge. The first annular support surface includes at least a first resilient member configured to contact the outer circumferential edge of the first optic and to be moved in a radially outward direction by the first optic relative to the longitudinal central axis. The resilient member assists in preventing substantial movement of remaining portions of the tubular optic support structure, for example, during assembly and any heat induced thermal expansion of the optic in use.
