Low Coherence Interferometry and Multi Wavelength Profilometry for Lens Assembly Process Control
By the use and combination of full field imaging and topography with single point IR temporal mode interferometry, Optical metrology systems can deliver all required 3D parameters for lens manufacturing and assembly. The multi wavelength approach allows to get topography at video acquisition speed rate while the IR interferometry gives thicknesses and gaps between lenses within an assembly.
