LuphoScan 260/420HD

Product catalog summary

Technology Overview: The document describes a high-definition optical metrology system for ultra-precision non-contact 3D form measurement of aspheric surfaces. The system uses a spiral scanning method with a probe that collects high-density 3D data by rotating the object on an air-bearing spindle while the sensor moves radially and axially. This setup allows for flexibility in measuring complex surface shapes, including steep slopes and inflection points. The MWLI® sensor technology enables the inspection of discontinuous optics and the LuphoSwap extension measures lens thickness and errors.

Accuracy: The LuphoScan platforms offer exceptional form measurement accuracy through a unique reference frame concept and referencing sensors based on the Abbe principle. The LuphoScan 260 HD platform has been optimized with new materials, improved sensor control, and real-time ambient condition monitoring, achieving an absolute measurement accuracy of better than ±50 nm (3σ) up to 90°. The reproducibility and noise floor of measurements have also been significantly enhanced.

Graph Analysis: A graph in the document illustrates the variation of Power and PV errors in repeat measurements of a calibration ball over 14 hours, showing variations of less than ±15 nm and ±5 nm, respectively.

Company Information: Taylor Hobson is a renowned manufacturer of precision measuring instruments, offering metrology support services, including preventative maintenance, design engineering, precision manufacturing, inspection services, metrology training, and UKAS calibration and testing. Contact information for various global offices is provided.

LuphoScan platforms are scanning interferometers based on an optical (non-contact) point probe that utilizes MWLI® technology (multi-wavelength interferometry). Technology During measurement the probe performs a spiral scan over the entire surface of the object under test and produces high density 3D data. Scanning is achieved by rotating the object by means of an air-bearing spindle whilst the sensor is moved radially and axially using linear stages. A rotary stage keeps the sensor normal to the object surface. The layout of movement stages provides high flexibility, even for uncommon surface...
