A foldable lens system attached to a protection case or cover that can be used as a telescope for mobile device rear camera. A compact lens system that can be easily stored. The lens holders are self-aligned concentrically to the rear camera through the alignment and recessed structure on the lens holders and the case. This system can be scaled through adding or removing some lens holders.

A camera device is provided, which is switchable between an unfolded state and a folded state. The camera device includes a first lens module and a second lens module. The first and second lens modules are rotatably connected and respectively have a first optical lens and a second optical lens. When the camera device is in the unfolded state, the first and second optical lenses face a first direction. When the camera device is switched from the unfolded state to the folded state, the second optical lens module is rotated from a first position to a second position with respect to the first optical lens module, and the second optical lens faces a second direction, wherein the first direction is opposite to the second direction.

Optical imaging systems are presented with high performance physical optics in conjunction with advanced image processing technique specifically tuned with respect to those physical optics to realize compact, very high resolution imaging systems. Clever geometric arrangements of lens elements and translation systems to effect motion between those arrangements support very compact storage modes and high performance imaging modes in the same device. As such, these imaging systems disclosed are particularly useful for photography and videography applications where highly portable and compact platforms are in demand. Systems which are small enough to be integrated with a common smartphone computing platform can produce very high resolution images comparable to those of high end digital single lens reflex DSLR systems.

A portable telescope that takes advantage of an offset optical pathway between the objective tube and eyepiece tube that allows adjustment of the eyepiece height independent of the objective tube elevation. A user-friendly, motorized, interactive, self-calibrating portable telescope with an offset optical path.

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.

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 portion in which a detachable panel 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 viewer is of a unitary construction in which the panels of the body portion and the panels of the viewing portion are die cut from a single piece of material and folded along fold lines to form the viewer.
