Descripción
The future large telescope for the Observatorio del Roque de los
Muchachos will have a 10 m diameter segmented primary made of hexagonal
elements (similar to the Keck I primary). The telescope optical
configuration is being selected to achieve excellent image quality and
low emissivity out to the mid-IR. The design includes provision for two
exchangeable secondary mirrors, one of which is to be an adaptive
secondary. In order to perform an independent optical calibration of the
segmented primary and the adaptive secondary mirrors, the telescope with
the adaptive secondary will be of the Gregorian type, whereas with the
conventional secondary it will have a Ritchey- Chretien configuration.
Current work to define both telescope configurations and to make them
compatible is presented in this poster.
