摘要: We present a highly compact and fast varifocal lens with aspherical tunability based on an active piezo-glass-piezo sandwich membrane. Using optimized geometry, improved fabrication compliant elastomer structures together index-matched optical fluid, we achieved outer diameter of just 9 mm (10 packaged) for clear aperture 7.6 mm. The range the focal power was -7 m−1 to +6 m−1, wavefront error around 100 nm response time between 0.1 0.15 ms.
