Sealed linear lens actuator with decentered holders for applications in clean environments.

Sealed linear lens actuator

This optical platform is the solution for precisely driving and positioning optics over long strokes in clean environments, like for the realization of focus or zoom functions in high power laser applications. 

Thanks to the presence of high quality bellows, the ball screw and guiding rods are fully encapsulated. This configuration ensures a clean optical path and thus guarantees extended and maintenance-free lifetime.

Main features


    Stroke (per lens):40 mm
    Unidirectional axial repeatability: ± 4 µm
    Lateral repeatability (per lens): ± 4.5 µm
    Angular repeatability (per lens): ± 0.1 mrad
    Dimensions:72 (base plate: 102) x 50 x 257 (base plate: 271) mm
