Thales SESO

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,
  • Olympus Digital Camera

    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.
