For Objective Lenses / SGSP-OBL

Stepping motor type objective lens actuator provides much longer travel than Piezo type actuators.

The 5-phase stepping motor can be connected to any of our standard stepping motor controllers.
With a compact and high resolution design this is best suited for incorporation into a microscope lens tube or an auto focus system.
Can be used for upright type and inverted type microscopes.
