Abstract

An optical joint for joining a first light transmissive material to a second light transmissive material. The joint comprises a transparent adhesive layer between the first and second materials, and an antireflection film between each of the first and second materials and the adhesive layer. The joint prevents Fresnel reflection which would otherwise occur between the light transmissive materials.
