New Scale’s small, precise and smart M3-F focus module enables precision lens focus in eSight Corp’s light-weight wearable vision enhancement system
Article in ECN magazine – Advances in piezo motor driver electronics reduce system power by approximately 40% while maintaining output power (motor speed) and optimal motor performance, and producing smoother, quieter motion.
Many optical applications require an off-axis sensor configuration to leave a clear aperture for light transmission through the center of a rotating optical element, which may be a polarizing optic, a micro filter wheel, a wedged prism or other component.
Hall effect position sensors with on-chip analog-to-digital conversion (ADC) lend themselves to very tiny systems. Using a novel implementation of these integrated linear position sensors, engineers at New Scale Technologies created a unique off-axis rotary position sensor that delivers absolute angular position information over a standard I2C serial digital interface. This sensor has a wide clear aperture, very small size and low power use. Coupled with New Scale’s tiny piezoelectric motors, it enables highly-miniaturized optical systems.
