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.

 

Speaker

Gilles Fresquet, Vice President, Optical Technologies, Fogale Nanotech Group

Gilles Fresquet has 35 years of engineering experiences in high tech. industry.

Back in the 80’s and 90’s, Gilles spent many years at Thomson and Motorola semiconductor in a variety of engineering and management roles in France and in the USA..

He then joined RECIF S.A (equipment supplier) as R&D manager and business development director.
