Freeform focusing system for microscopy


Microscopy

Moving two superposed lenses of particular shapes laterally in an optical device makes variable focus possible. This clever optical configuration, motorized by two Faulhaber 1020 stepper motors mounted on a flexible body, allows the elaboration of dynamic, robust and precise focusing systems with non-deformable optics.

Our systems, adapted to your environment

MPS Microsystems' optical platforms bring together several technologies that we have mastered for decades. Thanks to this expertise, we are able to adapt our systems to the various 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. Contact our engineers today to start your project.


Flat focusing mechanism

MPS has developed a backlash-free, flexure-based system that moves 2 lenses laterally in order to make fine focus adjustments and eliminate the risk of contact with the sample. The system has a full stroke of 2.5 mm and is driven in an open loop by 2 stepper motors attached to a miniature lead screw. Light barriers set the home position at the beginning of each operation. The position repeatability is below 2 microns. The simplicity of the system makes it very reliable, easy to connect and affordable.
