The invention of the current application is directed to a 3-dimensional viewing device with stereoscopic affect including a main linear body including at least one inner lining layer, and a mirror assembly. The at least one inner lining is positioned within the main linear body and the mirror assembly is positioned inside the main linear body where the perimeter of the mirror assembly is surrounded by the at least one inner lining. The mirror assembly includes at least two mirrors. The 3-dimensional viewing device with stereoscopic affect also includes an image holder assembly including a gear assembly, and an endcap including a viewing hole. The endcap is attached to a first end of the main linear body and the second end of the main linear body at least partially inserts into an opening in the image holder assembly.

A removably attachable optical device includes a clamp comprising an upper clamp member and a lower clamp member. When the clamp is mounted on a mobile device, the upper member extends over a device side to enable an orifice formed by the upper clamp member to be positioned over an aperture of the mobile device. An optical element housing has a portion configured to engage the an upper clamp member. A non-uniform optical element is rotatably mounted to the optical element housing. Rotation of the non-uniform optical element causes light passing through the non-uniform optical element as the non-uniform optical element is rotated to be correspondingly altered to create optical effects.

An imaging system having multiple imaging devices arranged in succession in the direction of an optical axis, including a first imaging device for generating a real intermediate image of an object on an intermediate image plane, a second imaging device for generating a virtual mirror image of the real intermediate image, the mirror image being laterally offset to the real intermediate image on the intermediate plane, and a third imaging device for imaging the real intermediate image and the virtual mirror image together as a real image on an image receiver surface to be arranged at an axial distance to the intermediate image plane. The imaging system has an optical filtering device for filtering the imaging of the real intermediate image and/or at least one of the virtual mirror images separately from each other. The imaging system includes the image receiver surface and a device for processing a real image captured by the image receiver surface. The processing device uses the image to determine positions in the direction of the optical axis of object region points, which are imaged by at least individual pixels of the pixels of the image.
