Optics systems presented are arranged as high-performance imagers particularly characterized by their exceptional compactness in view of image quality. A plurality of lens and let's and or doublets are configured to cooperate with related mount systems optimized for compactness. To achieve very high resolution imaging despite somewhat abbreviated compound lens design, these systems include use of lens array elements proximate to an imaging plane. So placed lens array devices may be designed with lens elements which invariably operate on incident wave planes with radial dependence. That is, the focusing strength of lenses from which these lens arrays are comprised may depend upon its distance from system optic axis. This enables an imaging correction function that counters distortion and other undesirable imaging errors typically present in a simplified compound lens systems. When used together and in conjunction with special-purpose collapsing lens mounting systems, an imaging system of very high fidelity and very compact weight size is achieved to great advantage in system when a premium on lens size is necessitated.

The present invention relates to a collapsible virtual reality viewer. Aspects of the viewer include a body portion and a viewing portion, each having a plurality of panels abutting fold lines. The viewer may be folded along the fold lines to move from an expanded configuration to a collapsed configuration when it is not being used. In one aspect, the viewer includes a detachable panel that is removeably coupled to the viewer along a plurality of perforations. Promotional material may be printed on or attached to the detachable panel. In another embodiment, the body portion and the viewing portion are each formed of a unitary construction in which the panels of each portion are die cut from a single piece of material and folded along fold lines to form the body and viewing portions, which are then secured together at one or more locations.

A large reflector inflatable telescope. The telescope has an inflatable hull with a conical lower portion and a hemispherical upper portion. The conical portion is transparent to electromagnetic waves so that radio or light waves can reach an inner reflector, which is interposed between the conical portion and the hemispherical portion. The presence of the inner reflector allows the conical portion and the hemispherical portion to be inflated at different pressures such that the reflector becomes spherical or parabolic. If desired, the reflector can be made adjustable with a membrane behind the reflector that provides electro-static force to shape the reflector.

A portable screen shade for a camera display includes a pre-cut, foldable cardstock sheet with four adjacent panels. Each panel has an irregular hexagonal configuration, with a larger base end tapering to a narrower viewing end. The base ends of the panels are interconnected along fold lines, with the end edges of the bases extending along a common plane. Each narrow end is spaced apart from an adjacent panel, with the narrow end edges also extending along a common plane. The sheet can be folded into a four-sided partial pyramidal frustum configuration, with an enlarged end configured to be located against the camera screen, and a narrower viewing end, with the sides of adjacent panels connected by an adhesive strip or tab-in-slot. Flap tabs springs extend across fold lines on pairs of the panels to maintain the screen shade in an expanded configuration, and enable it to be folded flat.

An optical apparatus includes a main body, a reflecting object lens pivotally connected to the main body and a cover pivotally connected to the reflecting object lens. The reflecting object lens is rotatable with respect to the main body within a first angle, and the cover is rotatable with respect to the reflecting object lens within a second angle.

A hand-held emergency vision device includes a hand-held emergency vision device having an enclosed tubular housing with a first end and a second end. The enclosed tubular housing has an expanded shape memory form. First and second clear members are provided at the first and second ends, respectively; and the tubular housing is compressible to an unexpanded compact form. The housing is releasably held in its compact form, and is self-expandable to its expanded shape memory form when released from its compact form.
