Diffractive Optics

  • Overview +

    Diffractive OpticsDiffractive Optics with Aspheric base forms are typically manufactured using Single Point Diamond Turning. 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 information below.
