Slit Mask Integral Field Units for the Southern African Large Telescope
Sabyasachi Chattopadhyay, Matthew A. Bershady, Marsha J. Wolf +1
Two fibre integral field units (IFU) are being built in the SAAO fibre-lab for the Robert Stobie Spectrograph's visible arm and the future red arm. Each IFU sits in its own slit-ma…
Optimum telescope focal ratios for microlens-to-fiber coupled integral field spectrographs
Sabyasachi Chattopadhyay, Matthew A. Bershady, Marsha J. Wolf +1
We describe the optimum telescope focal ratio for a two-element, three surface, telecentric image-transfer microlens-to-fiber coupled integral field unit within the constraints imp…
Observing the Sun as a star: Design and early results from the NEID solar feed
Andrea S. J. Lin, Andrew Monson, Suvrath Mahadevan +27
Efforts with extreme-precision radial velocity (EPRV) instruments to detect small-amplitude planets are largely limited, on many timescales, by the effects of stellar variability a…
The Prototype Telescope and Spectrograph System for the AMASE Project
Renbin Yan, Matthew A. Bershady, Michael P. Smith +7
We present the design of the prototype telescope and spectrograph system for the Affordable Multiple Aperture Spectroscopy Explorer (AMASE) project. AMASE is a planned project that…
Development and Characterization of a Precisely Adjustable Fiber Polishing Arm
Michael P. Smith, Sabyasachi Chattopadhyay, Andrew Hauser +3
The development of bare fiber or air-gapped microlens-fiber coupled Integral Field Units (IFUs) for astronomical applications requires careful treatment of the fiber end-faces (ter…
Optimization of telescope focal ratios for MLA-fiber coupled Integral Field Units
Sabyasachi Chattopadhyay, Matthew A. Bershady, Marsha J. Wolf +1
We have developed an analytic model for generic image transfer using microlens-coupled fibers to determine the telescope input beam speed that optimizes the lenslet clear aperture…
