SESO KNOW-HOW

SESO, partner of your industrial project
A skillfull engineering team
The perfect command of a large scale of technologies ...

• Mechanical design specially adapted to environmental constraints (thermal, vibratory,...)
  
  
• Optical design optimized according to manufacturing and integration methods.
  
  
• Photometric calculations
  
  
• Manufacturing of aspherical surfaces (of large diameters) :
              - by polishing machines
              - or by replication
  
  
• Manufacturing of large size X mirrors, with mechanical benders or piezo-electric system (active optics)
  
  
• Manufacturing of very high performances lenses (NA > 0,7 , limited by diffraction)
  
  
• Mirrors lightweightening
  
  
• "Super-polishing" technology
  
  
• Optical surface coating :
              - reflective,
              - anti-reflective,
              - high laser damage threshold (3ω)
              -metal high performance (Ag, Au, Al-MgF2, X-Ray)
  
  
• Polishing of a large range of substrates
  (glass, Copper, Aluminium, Beryllium, SiC, ZnSe, CaF2, Silicon, Germanium,…)
  
  
• High precision assembling and integration by high stability bonding techniques
  and molecular adhesion (optical contacting)
  
  
• High precision interferometric testing
