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…
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…
Fiber positioning in microlens-fiber coupled integral field unit
Sabyasachi Chattopadhyay, Matthew A. Bershady, Marsha J. Wolf +2
A generic fiber positioning strategy and a fabrication path are presented for microlens-fiber-coupled integral field units. It is assumed that microlens-produced micro-images are c…
