An ultrasonic variable optical focus lens which utilizes the refractive index difference of two immiscible liquids was developed. The profile of interface between the two liquids can change by radiation force of ultrasound so that the lens can act as a variable focus lens. The focal point could be controlled by the driving voltage, and the shortest response time of 6.7 ms could be achieved. The confocal image could be captured by sweeping the focal point in the light axis at 1 kHz. Three dimensional focal scanning could be also achieved by non-axisymmetric sound pressure field.
