Maximizing Optical Alignment Precision by Choosing the Correct Positioning Architecture

Advancements in silicon photonics and micro-optic technologies are driving automated alignment tolerances down to nanometer levels. Misalignment between optical components in today’s photonic devices directly impacts the quality of light transmission, and only a few micrometers of misalignment can result in final device power losses of 50% or more (Figure 1). Photonic device manufacturers are…

Top 3 Ways to Increase Your Positioning System’s 3D Accuracy

Positioning systems are used to automate almost every high-precision manufacturing process. Many of these processes occur in 3D. Some examples include positioning a part’s surface in 3D to be 100% inspected and laser cutting a feature along a complex 3D path. For these types of processes, it’s exponentially harder to achieve manufacturing tolerances in terms…

Improving Automation Performance

At some point automation hardware inevitably becomes obsolete. It’s hard to know exactly when to retrofit or redesign, but there are indications that cannot be ignored. Quite simply, when the system’s tolerances and throughput can no longer meet market demand, it is time to upgrade. If the tolerances of the previous generation system can only…

Advanced Motion Control for Durability, Part Characterization and Dynamic Mechanical Analysis (DMA)

This white paper reviews technologies used to produce motion and exert forces on a test specimen using Dynamic Mechanical Analysis (DMA) and related testing applications. Refer to Figure 1 for typical types of DMA testing. Generally, there is an interest when studying materials to understand their dynamic modulus (elasticity, tensile strength, etc.) that describes the…
