LUPHOScan 850 HD - Taylor Hobson
LUPHOScan 850 HD the world’s most versatile, non-contact 3D form measurement platform for advanced large diameter optical surfaces.
The LUPHOScan 850 HD is designed to perform ultra-precision non-contact 3D surface form measurement of rotationally symmetric surfaces (optics) such as aspheric lenses, spheres, flats and slight freeform. Key benefits of the profiler/equipment include fast measurement speeds and high flexibility with regard to uncommon surface shapes (e.g., flat apexes or profiles with points of inflection).
Revolutionary measurement capability
- Class-leading measurement flexibility – From 5 mm up to 850 mm (dia.) x 210 mm (height)
- Large work load – Up to 350 kg
- Highly accurate – Capable of accurate and repeatable form error measurements to < λ/20 (PV99) and <5 nm RMS*
- High data density – Data density up to 6 million data points for accurate analysis of mid-spatials at large diameters
- Freeform measurement – Up to ±8 degs for tangential slopes (radial slopes 90 degs)
- Almost every material – Transparent, specular, opaque, polished or ground.
Optimised technology for measurement accuracy and reproducibility
- Granite metrology frame – Homogeneous metrology frame ensures accurate compensation for thermal expansion with optimised design to minimise vibration
- Real time compensation of ambient conditions – 4 Temperature and 1 air pressure sensors
- Low system noise for the highest accuracy – Active anti-vibration deigned by TMC, delivers optimised isolation of the measurement loop
- Automatic centre and level – Consistently accurate results through complete measurement automation.
