Descripción
GREGOR is a new open solar telescope with an aperture of 1.5 m. It
replaces the former 45-cm Gregory Coudé telescope on the Canary
island Tenerife. The optical concept is that of a double Gregory system.
The main and the elliptical mirrors are made from a silicon-carbide
material with high thermal conductivity. This is important to keep the
mirrors on the ambient temperature avoiding local turbulence. GREGOR
will be equipped with an adaptive optics system. The new telescope will
be ready for operation in 2008. Post-focus instruments in the first
stage will be a spectrograph for polarimetry in the near infrared and a
2-dimensional spectrometer based on Fabry-Pérot interferometers
for the visible.
