An Integral Field Unit for the Binospec Spectrograph
Daniel Fabricant, Sagi Ben-Ami, Igor Chilingarian +5
Binospec is a wide-field optical (360 to 1000 nm) spectrograph commissioned at the MMT 6.5m telescope in 2017. In direct imaging mode Binospec addresses twin 8 (wide) by 1…
Off-axis Hartmann wavefront sensing for the GMT-Consortium Large Earth Finder (G-CLEF) red camera optics
Matthew C. H. Leung, Colby A. Jurgenson, Andrew Szentgyorgyi +10
The Hartmann test is a method used to measure the wavefront error in a focal optical system, wherein a mask with a pattern of small holes is placed at the system's aperture stop. B…
The Tierras Observatory: An ultra-precise photometer to characterize nearby terrestrial exoplanets
Juliana García-Mejía, David Charbonneau, Daniel Fabricant +4
We report on the status of the Tierras Observatory, a refurbished 1.3-m ultra-precise fully-automated photometer located at the F. L. Whipple Observatory atop Mt. Hopkins, Arizona.…
Binospec: A Wide-field Imaging Spectrograph for the MMT
Daniel Fabricant, Robert Fata, Harland Epps +14
Binospec is a high throughput, 370 to 1000 nm, imaging spectrograph that addresses two adjacent 8' by 15' fields of view. Binospec was commissioned in late 2017 at the f/5 focus of…
MMT & Magellan Infrared Spectrograph
Brian McLeod, Daniel Fabricant, George Nystrom +19
The MMT and Magellan infrared spectrograph (MMIRS) is a cryogenic multiple slit spectrograph operating in the wavelength range 0.9-2.4 micron. MMIRS' refractive optics offer a 6.9…
