A system and method that can be used to cover a portion (e.g., a clear aperture) of an optical element (e.g., a lens) during coating of another portion (e.g., a circumferential portion) of the optical element. This can be done to protect the clear aperture during coating of an adhesive protection layer proximate a circumferential edge of the lens without damaging or altering the clear aperture. The method can include the following steps. An optical element is held so that a first portion of the optical element is covered and a second portion of the optical element is exposed. A first coating is provided on the second portion of the optical element. The optical element is released from being held. A second coating is provided on the optical element. The first and second coatings are removed from the second portion of the optical element.
