LS-Series Linear Stages
About the LS-Stages
LS linear stages provide sub-micron accuracy, deriving their precise control by using closed-loop DC servomotors and employing high-resolution rotary encoders for positioning feedback. An optional linear encoder can be added to the unit to provide even greater positioning accuracy.
The stages utilize crossed-roller slides, precision lead-screws, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The units offer precise travel from 50 mm to 300 mm (2” to 12”). They can be used singly or stacked, vertically or horizontally, and can carry loads up to 4.5 Kg (10 lbs).
The units have built-in limit switches, and can be configured with a number of lead screw options as outlined in the table below. In standard rotary encoder configuration and using ASI’s MS-2000 control electronics, resolutions in the 50-to-100 nm range can be easily obtained. Repeatability factors of less than 300 nm RMS are also obtainable.
An optional linear encoder provides a scale resolution of 10 nm, and with a scale accuracy of ± 3 μm per length of scale.
