Progress of the conceptual design for the MOBIE imaging spectrograph for the Thirty Meter Telescope

Abstract

The Multi-Object Broadband Imaging Echellette (MOBIE) is the seeing-limited, wide-field multi-object optical imaging spectrograph planned for first-light operation on the Thirty Meter Telescope (TMT). Following the completion of a feasibility study and requirements review in December 2008, the MOBIE instrument project, based at the University of California Observatories (UCO) on the UC Santa Cruz campus, entered a conceptual design phase. In this paper, we describe the latest developments in the instrument optical design, and progress in the conceptual design of the optomechanical and mechanical elements for the instrument.

Design study of an image slicer module for a multiobject spectrograph

“…1 Corresponding instruments require huge optics, imposing technical challenges in manufacturing and supporting them. A specific example is the wide-field optical spectrograph (WFOS), [2][3][4][5] one of the TMT first-light instruments. It is being developed by an international collaboration led by the University of California Observatories.…”

Image slicer module for Wide Field Optical Spectrograph (WFOS)

“…Wide-Field Optical Spectrograph (WFOS) [1,2,3] is one of the first-light instruments of Thirty Meter Telescope (TMT), and has been developed in an international collaboration led by University of California Observatories. Its spectral resolving powers (R) are ~5,000 and ~1,000 in the high dispersion mode and the low dispersion mode, respectively.…”
