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...

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...
