OWL Instrument Concept Studies

Within the OWL Conceptual Design to be completed by ESO in 3Q 2005, ESO collaborates with external institutes in the study of a few instrument concepts which address primary scientific goals of the project.

Limited in scope but very much needed :

• To verify with actual instrument concepts the compliance and/or critical aspects in the interfaces and operation scheme of the present telescope design

• To identify critical issues and required R&D in the instrument development

Some of the concepts expected to evolve/merge in the more detailed studies to be carried out within the FP6 program for ELT
