Form Measurement of Diffractive Optics

Overview
Diffractive Optics with Aspheric base forms are typically manufactured using Single Point
Diamond Turning.

$Optics Applications - Measurement of Diffractive Optics$

In order to control this process so that sub-micron form accuracies can be achieved, Taylor Hobson’s Form Talysurf is an essential metrology tool.

Diffractive lenses and mirrors have a number of critical dimensional features, which determine the component’s optical performance. These include underlying aspheric form, zone height & diameter, and surface finish. Taylor Hobson have many years’ experience of meeting the measurement requirements of this highly specialist application. Detailed in the Talysurf links below.
