Herschel's Telescope

March 5, 2009
The Herschel telescope is a classic Cassegrain design with a 3.5-metre primary mirror and the secondary mirror. The manufacture, alignment and optical characterisation down to operational temperatures (70 K or -203 ºC) was completed in September 2006.

The telescope is now stored in the Astrium facilities in Toulouse waiting for integration to the Herschel satellite.
