Abstract
An electronic device may have optical components that each have first and second transparent layers such as first and second glass layers. The glass layers may have outer surfaces that face away from each other and inner surfaces that face towards each other. A polymer layer is formed between the inner surfaces of the glass layers. Along the periphery of each optical component, a hermetic seal is formed to protect the polymer material of the polymer layer. The seal may include one or more metal layers that are coupled to the first and second glass layers. For example, glass prism rings may be coupled to the first and second glass layers and metal may be coupled to the prism rings. The one or more metal layers may then be bonded to the metal on the prism rings, such as through soldering.
