Features

FEM Optimized Aluminum Body

Finite element method (FEM) was used to optimize the structural design of the ILS Series stage aluminum body allowing for extreme stiffness and minimizing bi-metal bending without compromising weight. The rigid body design reduces deflection under load allowing for the highest performance possible in an aluminum stage design. FEM optimized IMS stages are also available which offer longer travel ranges, higher load capacities, and larger moving platforms.

Economical Micro-stepping Stepper Motor

For less demanding applications, a stepper motor can be a more economical solution than a DC motor. A stepper motor operates using the basic principle of magnetic attraction and repulsion, converting digital pulses into mechanical shaft rotation. To improve the resolution and smoothness of motion, these stages feature micro-stepping, a method of electronically dividing a full-step of motion into a high number of partial steps.

Basic working principle of a micro-stepping stepper motor

Rotary Encoder for Improved Performance

Stepper motors are often run open-loop, with position attained by the number of commanded steps and micro-steps. This works reliably when used within their specified torque and speed range; however, the motion of a stepper motor becomes unpredictable outside their specified range. To avoid screw/motor coupling errors, position measurements of these stages are read on a 4000 cts/rev. rotary encoder located directly on the screw.

Recirculating Ball Bearing Slides

The recirculating ball bearing slides provide excellent payload capabilities and longer life with accurate linear trajectory. It mitigates the issue of ball cage migration, which is typically found on linear ball bearings or crossed roller bearings.

Backlash-free Precision Ground Ballscrew

These motorized linear stages include a preloaded, backlash-free, precision ground ball screw, which provides smooth, rapid motion with short step and settling time. The screw profile is designed to reduce heating effects, extending the life of the stage.

Other ILS Stage Features

A rigid top cover prevents damage to the drive train and protects it from dust and debris. ILS Series stages also feature an origin located at the center of travel for repeatable initialization, limit switches to prevent over travel, and elastomeric end-of-run dampers for smooth emergency braking.

Individual Stage Metrology Report is Included

Newport guarantees specification values which are measured and recorded following ASME B5.57 and ISO 230-2 standards. The typical performance values are two times better than the guaranteed specifications.

Multi-Axis Assemblies

Newport's standard motorized stages and components can be easily combined to create hundreds of possible multi-axis systems. Depending on the products and application, our standard assemblies are available with the following precision alignments:

  • Orthogonality to 50 μrad
  • Axes Coincidence to 20 μm
