Shape Measurement

Surface shape is the overall geometry of the area of interest, where the area of interest can vary according to the application.

For example, if you were measuring the topography of a micro-lens, “shape” might be described as a measurement of the lens’s curvature, as compared to a manufacturing specification.

Ultimately, this is a measure of the lens’s ability to focus correctly.

Other shapes of interest in materials sciences and engineering are planes, spheres, toroids, cylinders, parabolas and aspherical and free-form curves.
