Fast Steering Mirrors (FSM) - Design, Performance, And Tuning Of Piezo-Based Mechanisms
6/7/2022
In free space optical communication (FSO), large amounts of data are “beamed” between two points – on earth, on aircraft or between satellites in space. Fast steering mirrors (FSM) are one means to compensate for disturbances that could keep the laser beam from hitting its target receiver precisely.

Multi-Axis Stages: Why Custom Aligned, Tuned, Error-Corrected XYZ Assemblies Are Better
4/18/2022
Multi-axis precision motion at the micron or sub-micron level is required in many industrial automation processes as well as in test and metrology applications. Users of such motion systems often ask: Should I just get the individual components and bolt them together myself, or rather specify a complete XYZ system, mounted, aligned, and tested by a specialist? The answer depends on expectations, performance requirements, and budget.

What Is The Difference Between Parallel Positioners And Stacked Serial Kinematics?
9/27/2021
When faced with a multi-axis motion application, many users stack motion stages, and in fact that is a fine approach for assemblies of just a few axes. But as applications become more complex, so do the equivalent stacks-of-stages, and very real and practical considerations begin to come into play.
