Testing G-CLEF Fiber Efficiency: the Impact of using Adaptive Optics
G-CLEF is a state of the art echelle spectrograph for the Giant Magellan Telescope (GMT), expected to be completed for first light. Its good performance for seeing limited observations may be further improved with the future use of an extreme Adaptive Optics (AO) system to cancel out atmospheric dis...

| Sumario: | G-CLEF is a state of the art echelle spectrograph for the Giant Magellan Telescope (GMT), expected to be completed for first light. Its good performance for seeing limited observations may be further improved with the future use of an extreme Adaptive Optics (AO) system to cancel out atmospheric disturbances and optimize throughput. The goal of our project is to perform laboratory optical-bench experiments to simulate G-CLEF working with and without AO. We measure the efficiency of the G-CLEF fiber in both cases to compute the gain in using an AO system. |
