They are ideal for remote adjustment of sensitive, hard-to-reach optical components which can be influenced by the compressive and torsional forces imposed by traditional manual adjustment micrometers. Typical applications include optimizing the alignment of a laser cavity, zeroing in on coherence lengths or just adjusting the pointing of a beam over a long distance. Vacuum compatible versions to 10-6 hPa are available. Applications can also be automated using LabView or other software by sending basic commands to the NSC200 NewStep controller through the integrated RS485 port. NewStep actuators feature reliable open-loop stepper motors that provide 11mm travel, sub-micron minimum incremental motion and can be used for loads up to 28 N. To protect • Up to 11 mm motorized travel in a light, very compact design • Ideal for use as a micrometer replacement actuator in mirror mounts • Integrated limit sensors/switches prevent component and motor damage • Low friction design enables high sensitivity • Vacuum compatible versions to 10-6 hPa available Ultima morror mount with NSA12 actuators. NSA12V6 - Vacuum compatible up to 10-6 hPa Design Details Base Material Aluminum Drive Mechanism Direct drive, non-rotating lead screw Feedback Open loop, no encoder Drive Screw Pitch (mm) 0.3048 Reduction Gear None Limit Switches One limit switch on the motor side, use software limit for maximum travel limitation Motor 2 phase stepper motor, 48 steps/rev, 3 072 microsteps/rev. when used with NSC200 controller Cable Length (m) 3 Vacuum Compatibility Choose NSA12V6 for vacuum applications up to 10-6 hPa. Weight [lb (kg)] 0.2 (0.1) equipment damage from over-travel, NewStep actuators include a fixed, integrated minimum travel limit switch and a controller programmable soft limit for maximum travel. Additionally, the NewStep actuator also features a non-rotating tip that prevents wear and avoids periodic motion variations which may occur in other rotating tipped actuator products. Furthermore, the actuator incorporates a novel mechanism that virtually eliminates backlash, which is critical in applications such as optimization of beam alignment or optical scanning. NewStep actuators can be also used for absolute and repeatable positioning taks and feature better than 2.2 ìm uni-directional repeatability. The NewStep actuator's compact design (only 60 mm long x 30mm diameter) and standard interface is designed to be compatible with many Newport mounts and manual stages. NewStep actuators can only be used with the NSC200 NewStep Controller (see page 853).
