Abstract
An optical system providing improved control over light reflectivity is provided. The optical system includes an index-gap wedge prism to collect light escaping through the internal reflective surface of an optical element for recombination with light reflected by the internal reflective surface of the optical element. The index-gap wedge prism collects and redirects the escaped light back into the primary reflected path of the optical element to provide an aligned and correlated light across a range of applications, including applications where optical coatings on key surfaces may not be feasible.
