The MFA series miniature steel linear stages are designed for high thermal stability, stiffness and load capacity all in a very compact package. Relative to the stage's size, the stage is a low-cost option that offers precision motion for space-confined applications. They are offered in DC motor and stepper motor versions.

Newport's proprietary double-row linear ball bearing design with bearing ways that are directly machined into the structural frame of the stage result in very smooth travel, greater durability and longer life. Compared to other solutions that use commercial bearings, MFA linear stages have a higher load capacity and stiffness with low pitch and yaw errors.
DC motors are best characterized by their high speeds, smooth motion, good efficiency and a high power/weight ratio. The MFA-CC DC motor features an integrated gear-box and a motor-mounted rotary encoder. The high-resolution 2,048 cts/rev rotary encoder provides position feedback. Combined with a low-friction mechanical design, the MFA-CC delivers ultra-smooth motion with 100-nm sensitivity. Faster motion with higher reliability and lower backlash make DC Motor-driven stages ideal for applications requiring small incremental motion with high dynamic speed and good repeatability.
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, the MFA-PPD features micro-stepping, a method of electronically dividing a full-step of motion into a high number of partial steps.
A full steel body allows for a more compact design with exceptional stiffness-to-weight ratio, greater thermal stability and high load capacity.
The stage contains end-of-run limit switches on both ends to prevent damage to the stage from over-travel.
For more versatility and mounting options, top and base plates may be ordered separately to enable vertical (Z-axis) mounting and mounting to an optical table. For vertical mounting, note that the vertical (Z-axis) stage should be attached to the the
