Abstract
An optical assembly includes an optical device having an optical surface. The optical assembly further includes an encapsulant that substantially covers the optical surface. The encapsulant has a first layer (106) and a second layer (108). The first layer (106) has a first silicone-containing hot melt composition and a major surface (112). The second layer (108) has a second silicone-containing hot melt composition, the second layer (108) having a second major surface (110) in contact with the first major surface (112).
