A cloaking device comprises an object-side, an image-side, a cloaked region between the object-side and the image-side. An object-side optical component and an object-side tilt correction (TC) component are positioned on the object-side, and an image-side optical component and an image-side TC component are positioned on the image-side. The cloaking device is tilted relative to an object positioned on the object-side such that light from the object is incident on the cloaking device at an acute angle.
