    Abstract: Optoelectronic modules, such as proximity sensors, two-dimensional and three-dimensional cameras, structured- or encoded-light emitters, and projectors include optical assemblies and active optoelectronic components that are light sensitive or emit light. The optical assemblies are aligned to the active optoelectronic components via alignment spacers and adhesive. The alignment spacers include surfaces operable to limit the lateral migration of adhesive thereby preventing the contamination of the active optoelectronic components with adhesive. In some instances, small optoelectronic module footprints can be maintained without compromising the integrity of the adhesive.
