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. The object-side TC component redirects light from the object incident on the cloaking device such that the light propagates through the cloaking device generally normal to the object-side and image-side optical components. The image-side TC component redirects light propagating through the cloaking device back to normal to the object to form an image of the object on the image-side of the cloaking device which, if not for the TC components, would be distorted.
