Advanced measurement of multi-zone design optics, using a multi-zone design contact lens mould as an example. Non-contact metrology is desired for the complicated design of optics.
Measurement technique
- Software input - The user inputs all zone’s designs, together with all the measurement settings into one object file to make all the zone measurements in one go.
- Automated measurement - All the surface zones are measured using LUPHOScan.
- Analysis - The analysis for each zone can be made separately by entering the zone number and clicking ‘Evaluate’ button to calculate its corresponding surface zone form error.
In summary, LUPHOScan systems can be used to inspect the multi-zone design optics efficiently and precisely, which greatly helps the optic industry for improving the optic part quality.
Key features
Ultra-precision non-contact 3D form measurement of optical surfaces up to Ø850 mm.
The LUPHOScan is designed to perform ultra precision non-contact 3D form measurements of rotationally symmetric surfaces such as aspheric lenses, spheres, flats and freeforms.
