Aspheric optics are now specified for a wide variety of industrial, defence and consumer applications.
Taylor Hobson is the metrology provider of choice for aspherics manufacturers.
Single-Point Diamond Turning (SPDT) allows high precision aspheric optics to be manufactured quickly and efficiently. Sub-wavelength form accuracy specifications mean that metrology is critical to the manufacturing process. Taylor Hobson’s Form Talysurf PGI Aspherics Measurement System sets the global standard for optics users, delivering form accuracies as low as 1/10 Angstrom.
Diffractive Optics
Diffractive 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.
