ABSTRACT:
An optical element is disposed between cover glasses, and an optical coupling liquid is injected between the optical element and the cover glasses to form an optical package. An adhesive provides a liquid tight seal between the cover glasses. The optical element is a retarder, filter, polarizing film, or other optical element. Spacers are placed between the optical element and cover glasses to maintain space between the optical element and the cover glasses and assist in distribution of the optical coupling liquid. Applications include prism assemblies and other optical products. The invention may also be applied to joining optical components with liquid joints. For example, an optical switch includes a controllable retarder in a liquid filled joint.
