A zoom lens includes: a first lens group having a positive refracting power; a second lens group having a negative refracting power; a third lens group having a positive refracting power; a fourth lens group having a positive refracting power; and a fifth lens group having a positive refracting power and configured of sub lens groups. The tape springs are fabricated such that they are stable when wrapped around a cylinder or when deployed and have a higher energy state when stowed than when deployed. In this subsystem, a solenoid valve bleeds off pressurized fluid to move the first valve from a fully opened to a partially closed position. The method includes coating at least one fiber roving with a polymer resin, traversing the coated roving through an impregnation zone of an impregnation section to impregnate the roving with the resin, and applying an external pressure to the impregnation zone.
