The present disclosure describes optical and optoelectronic assemblies that, in some cases, include screen-printed micro-spacers, as well as methods for manufacturing such assemblies and modules. For example, an optoelectronic device mounted on a substrate can include an optical sub-assembly including a first optical element and a first micro-spacer on the optical element. The optical sub-assembly can be disposed over the optoelectronic device, with a first air or vacuum gap separating the first optical element from the optoelectronic device, and the first micro-spacer laterally surrounding the first air or vacuum gap.

Optical and optoelectronic assemblies including micro-spacers, and methods of manufacturing the same

The present disclosure describes optical and optoelectronic assemblies that, in some cases, include screen-printed micro-spacers, as well as methods for manufacturing such assemblies and modules. For example, micro-spacers can be applied on a first optical element layer, and a second optical element layer can be provided on the first micro-spacers. By providing the second optical element layer on the first micro-spacers, the second optical element layer and the first optical element layer can be separated from one another by air or vacuum gaps each of which is laterally surrounded by a portion of the first micro-spacers.
