Singulation and edge-sealing of multilayer polymer eyepiece

Abstract

Fabricating a multilayer optical component includes obtaining a substrate having a multiplicity of polymer layers and cutting the substrate with a CO2 laser to yield a multilayer optical component having a first surface, a second surface opposite the first surface, and a blackened edge along a perimeter of the multilayer optical component. The multiplicity of polymer layers is sealed along the blackened edge. The resulting multilayer optical component includes a multiplicity of polymer layers and a blackened edge seal around the multiplicity of polymer layers. The blackened edge seal includes polymer melt from the multiplicity of polymer layers.
