摘要： An optical device, such as an eyepiece, including multiple layers of waveguides. The optical device can include an edge sealant for reducing light contamination, a lamination dam to restrict the wicking of the edge sealant between layers of the optical device, and venting gap(s) in the sealant and dam to allow air flow between the exterior and interior of the eyepiece. The gap(s) allow outgassing from the interior of the eyepiece of unreacted polymer and/or accumulated moisture, to prevent defect accumulation caused by chemical reaction of outgassed chemicals with the (e.g., ionic, acidic, etc.) surface of the eyepiece layers. The gap(s) also prevent pressure differences which may physically deform the eyepiece over time.

摘要： Embodiments of the present disclosure are directed to an optical device, such as an eyepiece, including multiple layers of waveguides. The optical device can include an edge sealant for reducing light contamination, a lamination darn to restrict the wicking of the edge sealant between layers of the optical device, and venting gap (s) in the sealant and darn to allow air flow between the exterior and interior of the eyepiece. The gap(s) allow outgassing from the interior of the eyepiece of unreacted polymer and/or accumulated moisture, to prevent defect accumulation caused by chemical reaction of outgassed chemicals with the (e.g., ionic, acidic, etc.) surface of the eyepiece layers. The gap(s) also prevent pressure differences which may physically deform the eyepiece over time.
