Lens system having resilient members to axially position optics

摘要

An optical lens cell, especially useful in projection televisions, includes a tubular optic support structure having an interior with a longitudinal central axis and a first optic support surface extending around the longitudinal central axis. The first optic support surface receives a first optic having an outer circumferential edge and a first mounting surface portion adjacent the circumferential edge. The mounting surface portion of the first optic extends transverse to the longitudinal central axis. A plurality of raised surface members are provided on the optic support surface. At least one resilient member extends transverse to the longitudinal central axis and is configured to contact the mounting surface portion of the first optic when the first optic is positioned adjacent the optic support surface. The resilient member applies a biasing force against the mounting surface portion of the first optic along the longitudinal central axis to force the first optic against the raised surface members of the first optic support surface.
