Product Overview:

ASI LS-50A Motorized Stage Product Overview:

The LS-50 can be attached to an ASI XY stage to provide extremely precise XYZ positioning

The LS linear stage provides sub-micron accuracy, and derives precise control through the use of closed-loop DC servomotors employing high-resolution rotary encoders for positioning feedback. An optional linear encoder can also be added to the unit to provide even greater positioning accuracy. The stage utilizes crossed-roller slides, precision lead-screws, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The unit offers 50 mm of precise travel, and can be used either vertically or horizontally, and can carry loads up to 4.5 Kg (10 lbs).

The unit can be configured with a number of lead screw options as outlined in the table below. In our standard rotary encoder configuration, and using ASI's MS-2000 control electronics, resolutions in the 50-to-100 nm range can easily be obtained. Repeatability factors of less than 300 nm rms are also obtainable.

The optional linear encoder provides a resolution of 20 nm and can be used to provide the ultimate feed back device to increase these factors to a greater degree. Actual resolution & repeatability factors vary somewhat with the load so please contact ASI for these specifications.

The MS-2000 controller accepts industry standard commands, provides automatic backlash correction, and allows RS-232 or USB communication with a host computer.

ASI LS-50A 50mm DC Servo motor driven linear stage for use with LX-4000 or MS-2000 controller. This has the 0.635 mm (extra fine) lead screw pitch option which gives:
