Achromats Specification Guide
IEEE GlobalSpec

Achromats are optical lenses designed to minimize chromatic aberration. Achromats are also known as achromatic lenses. Chromatic aberration is a type of optical distortion which occurs when a lens fails to focus all colors to the same convergence point. This distortion is often recognizable as...

Piezo Motors: Principle of Operation for Engineers
Johnson Electric North America, Inc.

How it Works The Piezoelectric effect in piezoceramics converts electrical field to mechanical strain. Under special electrical excitation drive and ceramic geometry of Nanomotion motors, longitudinal extension and transverse bending oscillation modes are excited at close frequency...
