3D Form Measurement of High Quality Optical Surfaces

Taylor Hobson has unveiled its unique ultra low noise LuphoScan platform for 3D form measurement of high quality optical surfaces. The new generation instruments provide an industry first with instrument accuracy better than ±50 nm (3σ) on sample slopes up to 90°. By a significant reduction in noise and enhanced reproducibility, Taylor Hobson has addressed the rapidly advancing needs of lens designers and manufactures.

LuphoScan form measurement system revolutionized non-contact measurement of optical surfaces.

Optical Form MeasurementInnovation is the heart of our business,” said Jürgen Petter, Ph.D., Business Director of Luphos, Taylor Hobson Ltd. “The introduction of the first LuphoScan form measurement system revolutionized non-contact measurement of optical surfaces. The LuphoScan HD not only continues that tradition by taking measurement accuracy to the next level, but reflects the evolution of the optics industry and meets the needs of engineers and designers who rely on these instruments for the daily demands of optics manufacturing.”

Taylor Hobson products are underpinned by decades of measurement experience, ultra-precision manufacturing expertise and FEA optimised design, providing low noise and near flawless movements and measurements. The LuphoScan HD takes advantage of real time temperature compensation, guaranteeing highly accurate, reproducible results. This ensures the stability and accuracy even under the most adverse environmental conditions, such as in manufacturing areas.

The LuphoScan 260 HD is ideal for applications where the highest accuracy is required and essential to the manufacturing process. This is most beneficial for surfaces with steep slopes, with varying pitch directions, and small surfaces, such as moulds for smartphone lenses. The absolute measurement capability of the MWLI® sensor technology enables LuphoScan 260 HD instruments to inspect segmented lenses, annular lenses, asphero-diffractive lenses and axicons. Software modules can also be combined in order to measure a segment of an asphero-diffractive lens with a hole in the centre. LuphoScan HD represents a new era of metrology instrument with highest level of reliability for parts with large spherical departures and with extreme shot-to-shot stability.
