The Société Européenne de Systèmes Optiques (SESO) specializes in developing and manufacturing leading edge opto-mechanical components and systems, and is presently recognized worldwide as a leading supplier of opto-mechanical products to industry, space groups, government and military agencies.  SESO has the technologies for:

• DESIGN AND ENGINEERING - With its know-how, its knowledge of sources of light, and its experience as a main contractor, SESO has access to a large panel of technology in the following fields:
  • Thermal analysis
  • Mechanical structures including composite materials
  • Electronics for detection, imaging and control systems
  • Opto-electronics
• OPTICAL DESIGN
• MECHANICAL DESIGN
• ROUGH POLISHING
• POLISHING
• FINE POLISHING
• OPTICAL COATING
• INTEGRATION
   

SESO also has the facilities necessary to manufacture its products including (non exhaustive list):

• Aspherical surfaces/mirrors or systems with aspherical surfaces
• Lightweighted mirrors
• Mirrors for Synchrotron (X-ray mirrors) : transport and focalisation of X-Ray beams
• Lenses
• Low roughness surfaces, from UV up to IR objectives
• Polishing of complex aspherical optics (on and off-axis), including direct off-axis mirrors
• Polishing of all type of material used for the aspheric mirrors: Zerodur, ULE, SiC, Silica, Al, Si, Ge…
• Thin film/optical coating
• Integrating of opto-electronic test benches
• Integrating of accurate optical components (cementing, contacting)
• Interferometric measurement
• Roughness measurement
   

SESO general management developed a quality system covering all of the company’s activities from the proposal stage to the after-sale follow-up including design, purchasing, manufacturing, inspection, delivery and installation.
