OPTICAL DEVICE ALLOWING CREATING OPTICAL AESTHETIC AND TECHNICAL EFFECTS Russian patent published in 2021 - IPC G04B19/26 

FIELD: optical devices.

SUBSTANCE: invention relates to an optical device. An optical device comprising a transparent support (98) having an upper surface (100) and a lower surface (102) that extends at a distance from the upper surface (100), this transparent support (98) forming a flat-concave lens (108) bounded on the first side by a flat surface (110), and on the second side opposite to the first side by a concave surface (112), while the optical device also contains a shutter (94), which is located under the concave surface (112) of the transparent support (98) at a distance from it, and, finally, the optical device contains a substrate (106) located behind the shutter (94), and the optical device is configured to be formed using a plano-concave lens (108) images of the edge of the shutter (94) with the image of an object located on top of the flat surface of the specified plano-concave lens (108).

EFFECT: providing the possibility of creating optical effects.
