Tubular optical system with perfect co-axiality for applications requiring constant alignment (+/-1 µm) over the entire stroke, low angular variations, and very long lifetime without need of maintenance
Coaxial lens actuator
This very compact optical system with an original design allows two groups of lenses to be moved perfectly coaxially over several millimeters. It is particularly recommended for applications requiring a constant alignment precision when moving the lenses. The perfect coaxiality of the lens holders is guaranteed by a common bore machined in a single operation. Numerous dimensional modifications allow a perfect adaptation to the optical design related to its application. Due to the use of perfectly adjusted ball cages, its low-friction translation mechanism is best suited for intense use and offers an unequalled lifetime without any particular maintenance.
