IEEE Conference on Optical MEMS and Nanophotonics 2009, Clearwater Beach, USA, 17-20 August 2009, pp 39-40978-1-4244-2382-7http://hdl.handle.net/10204/3953Copyright: 2009 IEEEIn this paper the authors compare the performance and optical quality of two types of adaptive fluidic silicone-membrane lenses. The membranes feature either a homogeneous thickness, or it is shaped resulting in an inhomogeneous cross-section. The lens systems incorporate a piezo actuator which is operated in a regime of ±40 V. The shaped membrane lenses show lower wave front errors than the planar ones, down to 24 nm. However, the system with a planar membrane achieves a larger refractive power ranging from +19 to -14 dpt. It also shows a shorter full scale response time (tplanar = 23.9 ms) compared to the shaped membrane (tshaped = 35.4 ms).enAdaptive lensWave front errorShaped membraneSilicone-membrane lensesPlanarOptical MEMSNanophotonicsConference PresentationSchneider, F., Waibel, P., & Wallrabe, U.
