Laser guidance system
Developed and manufactured by MPS Microsystems based on customer specifications, this lens actuator forms an essential component of a laser guidance system for unmanned flying objects. It enables 2 lens groups to be displaced individually over a total range of 48 mm and makes it possible to focus a laser over a distance of several kilometres.
The main technical difficulty inherent to this actuator lies in meeting very stringent requirements for alignment between the two lens groups (< 10 µm) and in maintaining a very small tilt of the lenses over their entire stroke (lateral deviation < 2 µm).
The key part making it possible to ensure such specifications is a frame machined by milling from an aluminium block, into which the 2 drive systems are fastened. These systems each consist of a Ø16 mm brushless motor and a Ø4 mm ball screw with an axial play of less than 5 µm. Backlash-free and frictionless sliding of the lens holders is ensured by standard L306 linear ball bearings manufactured by MPS Microsystems.

MPS Microsystems' opto-mechanical platforms bring together several technologies that we have mastered for decades. Thanks to this expertise, we are able to adapt our systems to the different applications for which they will be used.
Our platforms are modular in their dimensions, type of motor, length and diameter of the ball screws, number of lenses and many other characteristics. Whatever your requirements and constraints are, MPS will take them into account. Thus, we are certain to be able to offer you a system perfectly adapted to your environment.
