Area of Science:

Micro-optics and nanotechnology
Surface science and engineering
Materials science

Background:

Microlens arrays (MLAs) and artificial compound eyes (ACEs) are crucial miniaturized optical components.
Their optical performance degrades significantly when exposed to moisture (fog, dew, rain) or contaminants in humid environments.

Purpose of the Study:

To review fabrication strategies for superwetting MLAs and ACEs.
To demonstrate the integration of superhydrophobic and superoleophobic microstructures with MLAs.
To highlight the benefits of superwetting properties for optical components.

Main Methods:

Categorizing fabrication strategies into hybrid patterns (MLA + superwetting domains) and direct nanostructure formation on microlenses.
Integrating superhydrophobic and superoleophobic microstructures onto MLA surfaces.

Main Results:

Superwetting properties were successfully imparted to MLAs and ACEs.
Fabrication methods include hybrid patterns and direct nanostructure formation.
Superhydrophobicity/superoleophobicity provides liquid repellence and self-cleaning capabilities.

Conclusions:

Superwetting MLAs and ACEs maintain excellent optical performance in humid or liquid environments.
These components offer liquid repellence and self-cleaning functions.
Significant applications are anticipated in optical systems operating in challenging environments.
