This miniaturized system allows to move 1 to 3 sets of lenses very precisely over a stroke of several centimeters. The design of this miniaturized optomechanical system has been optimized to ensure perfect alignment of the lenses and to minimize their tilt throughout the movement. This system mainly consists of high-precision MPS and FAULHABER modules, such as brushless or stepper motors, precision ball screws with double nuts and linear ball bearings. It is particularly suited for focusing a laser over a long distance, for example for the guidance of unmanned flying objects or for communication between flying objects. Such a system is also ideal for moving optics in stereoscopic surgical glasses. The number of lens sets, lens size and stroke can be configured to the customer's liking.
