Abstract: The following invention relates to an optical device for use in a system that requires optical zoom or focus abilities, particularly for providing pre-set zoom parameters with a very low energy requirement. There is provided an optical magnification device comprising at least one pair of optically aligned deformable reflectors, wherein each reflector pair has at least two configurations, wherein selection of a first and a second configuration of said deformable reflector pairs provides pre-defined magnification states, such that in any configuration one reflector is substantially concave and the other is substantially convex; at least one controller may cause both the reflectors to move between said at least two configurations.

Abstract: The following invention relates to an improved lens apparatus for use in a head up display (HUD), particularly for providing a deployment means for a HUD.The deployment device comprises a servomotor and cord assembly to move the carrier, wherein the carrier is biased, such that the first action is to deploy the lens, and then cause subsequent movement of the lens through an arc.
