Miniature lens actuator for eye tomography and laser eye surgery


Miniature lens actuator

Eye tomography as well as cataract and refractive surgery require very precise focusing of the laser beam. MPS has developed very high-precision miniature lens actuators for a manufacturer of ophthalmic devices. These actuators consist of a 6 mm diameter micro stepper motor, a pre-loaded screw-nut system and a linear guideway. The system is designed in such a way that it is able to compensate for the imperfection of axes alignment. The most stringent requirement is to find the home position with a precision of 1 µm between each measurement.
