US Patent 7583289 Optical block assembly

Optical block assemblies having single or multi-stage folded light path lens assemblies that may be implemented to allow an optical block assembly to occupy significantly less space and/or present reduced rotational inertia to an electrical articulating mechanism. An optical assembly may be so configured for closed circuit television applications or in any other suitable video imaging application including, but not limited to, applications involving non-articulated or articulated cameras such as normal filming (e.g., motion picture film cameras or studio television cameras), camcorders, military targeting or imaging devices, etc.
