Driving electrically tunable lenses

Optotune's electrical lenses are current controlled. There are several options for current drivers ranging from regular lab power supplies to tiny VCM driver ICs including a high-precision USB driver with a resolution of 0.1mA, which includes read-out of ingetrated temperature sensors over I2C.
