A customer specialized in the assembly of microelectronic components for demanding applications including space, implanted medical, aeronautics, defense and nuclear, approached PIS\u00c9O with a specific need. This customer had to integrate performance control into its production flow by means of an optical measurement bench equipped with laser sources.<\/p>\n\n\n\n
The complexity of this bench was linked to the particularities of the components to be tested, resulting in tight technological constraints. The design and installation of such a bench calls for in-depth knowledge in several fields including physical interactions between light and matter, optical technologies and manipulation of precision optical components and laser technologies.<\/p>\n\n\n\n
This customer, not having the skills in optical test bench engineering, called on PIS\u00c9O to make one. The project was segmented into three parts: specification, design, and construction and validation.<\/p>\n\n\n\n
Laser light has very specific properties, such as a precise wavelength and coherent and directed light emission. The components to be tested, due to their structure, respond differently to light stimuli depending on these properties. The measurement bench must therefore be able to control quantities such as power, beam direction, polarization, modulation and time profile.<\/p>\n\n\n\n
