Space Optics

The Space market takes a prominent place in Thales SESO activity. A large product line of Korsch Telescopes was developed through the years. We produced 8 sets of flight models between 2005 and 2012 and 4 of them are currently in orbit. Our Investment in R&D and in new technologies keeps us in the fore front of performance with improvements in Wave Front Error and Weight.

ETGAR Project – Korsch Telescope
Thales SESO Manufactured (i.e. lightening, polishing, coating) the 2 sets of 3 mirrors composing the Korsch-type telescope. The largest mirror is aspherical with a diameter of 700mm and a roughness below 5 Å on the whole surface. The others are hyperbolic and elliptic off-axis. The last set was delivered in March 2010 to Israel.
