The Large Fiber Array Spectroscopic Telescope: trade-off study of high-resolution spectrometer architectures

A combination of large collecting aperture telescopes and highly efficient high-resolution spectrometers is crucial for key cases in exoplanet science in particular the search for biomarkers. Here, we present a design study exploring high-resolution spectrometer concepts for the Large Fiber Array Spectroscopic Telescop...

The Large Fiber Array Spectroscopic Telescope: status update of the prototype telescope

The Large Fiber Array Spectroscopic Telescope, a part of the Eric and Wendy Schmidt Observatory System (LFAST), is designing and building a new optical telescope composed of an array of small “unit telescopes”, which can be replicated economically and at scale to produce an arbitrarily large incoherent aperture. Our fi...

Mass production of the LFAST 0.76m primary mirrors: fabrication and on-sky control

The Large Fiber Array Spectroscopic Telescope is ramping to high volume manufacturing of 0.76m, f/3.46 spherical mirrors that focus light into fibers combined at a central spectrograph. Separating the collection aperture into individual mirrors allows for significantly reduced cost and mandates a fabrication regime whe...
