    Abstract: A sensor for emitting or receiving light rays includes a clear substrate having a first surface, and an applique attached to the first surface of the clear substrate. The applique includes a transparent fluoropolymer sheet of fluorinated ethylene propylene having a first surface facing the first surface of the clear substrate, and a pressure sensitive optically clear acrylic adhesive disposed on the first surface of the fluoropolymer sheet. The pressure sensitive acrylic adhesive adheres the transparent sheet to the first surface of the clear substrate, and exhibits a peel strength of between 1 and 3 lbs/in. The first surface of the fluoropolymer sheet is treated for adhesion prior to applying the pressure sensitive acrylic adhesive thereto.
