02.18.26 -- Extreme Metrology, Surface Flatness And Wavefront Error, Opal Diffusers & More

Who Is Shaping The Direction Of Metrology?

Government involvement in metrology can boost innovation, collaboration, and public trust, as well as foster economic growth. However, it also poses challenges like compliance costs and trade barriers.

SPOTLIGHT ON METROLOGY

Extreme Metrology: Big Science Requires A Nano-Perspective

Extreme metrology applications involve more than enough unknown variables. Instrumentation whose performance has been proven should not be one of them.

Micro-Molding Metrology

Modern advances in computer aided design allow mechanical engineers to build virtual geometries smaller and more complex than ever imagined only a few years ago.

INDUSTRY INSIGHTS

Surface Flatness And Wavefront Error

The concept of surface flatness and wavefront error in the context of optical components is explained, including how these properties are measured, defined, and how they impact optical performance.

Open, Modular Control Platform For Multiple Drive Applications

Dr. Julien Mintenbeck, our Head of Platform Development Electronics, gives insights into the genesis and current state of PI's modular control platform.

Opal Diffusers – Uniform White Light For Tailored Illumination

Customizable Opal Diffusers, crafted from opal glass, offer precise control over thickness and size, providing uniform white light for tailored illumination needs.

FEATURED EDITORIAL

How High-Speed Optical Metrology Fuels The Digital Twin Ecosystem

By capturing fast-changing geometries and transient effects, optical systems keep digital twins syncronized under real operating conditions. This measurement speed supports tighter feedback loops between physical processes, simulations, and control systems. As a result, digital twins move from static references to active decision engines grounded in measurable reality.
