The Talysurf PGI 3D Optics metrology device from Taylor Hobson was designed to provide a broader measuring range of aspheric lenses of up to 200 mm and to enhance the 3D capability.
The optical machine, designed by PGI Blu, provides a wider range of part diameters and supports 3D measurement. The repeatability factor can be lower than 50 nm. The instrument can be used to determine the optics utilized in a wide array of devices such as blu-ray players, cell phones, digital cameras, projectors and medical equipment. In addition, the instrument can be used in rescue systems, military and security applications where infra-red thermal imaging is essential. Users can measure optics from the smallest dimension to the highest numerical apertures using the device.
The instrument delivers automation capabilities that make it ideal for use in factory floors and research and development purposes. Owing to high operational efficiency and simplicity of design, the instrument renders increased cost savings for manufacturing companies.
Users can execute a series of measurements and calibration using the embedded software in the system. The instrument enables users to view the components without any further measurement study. The PGI 3D Optics is suitable for measuring the 3D images of lenses and moulds that are shallow and steep sided.
