Freeform Optics

  • Overview +

    Freeform OpticsNon Rotationally Symmetric (Freeform) optics are becoming increasingly widely used for both civil and military applications. Advanced manufacturing technologies such as Ultra Precision Raster Milling allow a wide variety of shapes to be created.

    Popular applications include Printing / Scanning, Head-Up Displays and Ophthalmics. Taylor Hobson's market-leading Form Talysurf measurement system has long been the system of choice for 3D measurement of rotationally symmetric optics this technology is now meeting the challenge of Freeform Optics.

    With the trend towards freefrom optics in the marketplace and the growing need for increasingly complex measurement solutions, Taylor Hobson continue to produce contact and non-contact systems that meet freeform measurement requirements.
