Strain tunable optics of elastomeric microlens array

摘要: Abstract Microlens arrays (MLAs) have attracted great attention with their important applications in many fields, such as optical communications, organic light emitting diodes (OLEDs), thin film photovoltaic cells, and novel bio-inspired devices. The dynamically tunable MLAs whose properties can be changed a controllable manner are especially desirable some recent developments. In this study, very simple tuning method via mechanical stretching is proposed to tune the optics of elastomeric MLAs. Theoretical mechanics studies combined demonstrate tunability under both uniaxial equibiaxial stretching. results show that extremely large range focal length achieved using method. This theoretical study provide implications not only design MLAs, but also developments require elements.
