Addressable microlens array for parallel laser microfabrication.
Parallel processing in femtosecond-laser-based microfabrication is demonstrated using a microlens array in conjunction with a liquid-crystal spatial light modulator (SLM). A portion of the SLM is mapped onto each individual lenslet in the array and can be used to effectively switch foci on and off for fabrication. In addition, the technique allows for homogenizing the intensity of the array of ...
متن کاملThe Effects of Profile Errors of Microlens Surfaces on Laser Beam Homogenization
Microlens arrays (MLAs) are key optical components in laser beam homogenization. However, due to imperfect surface profiles resulting from microfabrication, the functionalities of MLAs in beam modulation could be compromised to some extent. In order to address this issue, the effects of surface profile mismatches between ideal and fabricated MLAs on beam homogenization were analyzed. Four types...
متن کاملTunable Microfluidic Optical Devices with Integrated Microlens Array
The interest in dynamically tuning light has attracted great attention to the fabrication of tunable microlens arrays. Here we discuss the fabrication and characterization of a simple, robust, yet tunable microfluidic optical device with integrated microlens array. The microfuidic device with desired channel structure was micromachined on a polycarbonate plate with a resolution up to 100 μm, fo...

متن کاملTunable liquid-filled microlens array integrated with microfluidic network.
An elastomer-based tunable liquid-filled microlens array integrated on top of a microfluidic network is fabricated using soft lithographic techniques. The simultaneous control of the focal length of all the microlenses composing the elastomeric array is accomplished by pneumatically regulating the pressure of the microfluidic network. A focal length tuning range of hundreds of microns to severa...
