New Scale Technologies (Victor, NY) offers the UTAF (ultra-thin auto focus) piezoelectric lens actuator module that measures 8.5 × 8.5 × 3.8 mm. The module integrates the company’s UTAF piezoelectric beam motor with a drive IC and position sensor IC for closed-loop motion control. A pin bushing system moves the lens in a straight line with dynamic tilt of less than 0.1 degree, a requirement for high-megapixel cameras and imaging systems. A flexure preload or magnetic preload system produces substantially zero additional friction in the bearing guide, irrespective of the location along the optical centerline. This allows the module to lift a mass at least three times greater than the typical lens mass of 0.25 grams, insuring a low sensitivity to gravity orientation for the camera system.
