Motorized Actuators

Optosigma Motorized Actuators are standalone motor-driven components that add automated positioning capability to existing optical mounts, mirror mounts, and breadboard setups without replacing the entire stage assembly.

Stepper motor linear actuators:
– Travel range: 10 mm to 100 mm depending on model
– Resolution: full-step 5 um; half-step 2.5 um; with microstepping down to 0.1 um
– Lead screw pitch: 0.5 mm/rev to 2 mm/rev
– Holding torque: provides position lock without brake for vertical loads
– Speed: 0.1 mm/s to 10 mm/s; set by pulse rate from controller

Stepper motor rotary actuators:
– Worm gear or direct drive configurations
– Resolution: 0.01 degree per step with worm gear reduction
– 360 degrees continuous rotation; homing via optical limit switch
– Used for: polarizer rotation, filter wheel, beam chopper, laser diode angle

DC servo actuators:
– Closed-loop control with quadrature encoder feedback
– Higher speed than stepper; constant velocity scanning
– Position repeatability: 0.5 um

Controller options:
– Single-axis desktop controller with USB or RS-232 interface
– Multi-axis controller for XYZ automation
– SHOT series controllers with Optosigma OPTICS software and LabVIEW drivers

NewRoad provides Optosigma motorized actuators in Israel for automated optical alignment, remote operation, and lab automation in photonics and spectroscopy labs.
