Descripción
The 4-m aperture Advanced Technology Solar Telescope (ATST) is the next
generation ground based solar telescope. In this paper we provide an
overview of the ATST post-focus instrumentation. The majority of ATST
instrumentation is located in an instrument Coude lab facility, where a
rotating platform provides image de-rotation. A high order adaptive
optics system delivers a corrected beam to the Coude lab facility.
Alternatively, instruments can be mounted at Nasmyth or a small
Gregorian area. For example, instruments for observing the faint corona
preferably will be mounted at Nasmyth focus where maximum throughput is
achieved. In addition, the Nasmyth focus has minimum telescope
polarization and minimum stray light. We describe the set of first
generation instruments, which include a Visible-Light Broadband Imager
(VLBI), Visible and Near-Infrared (NIR) Spectropolarimeters, Visible and
NIR Tunable Filters, a Thermal-Infrared Polarimeter & Spectrometer
and a UV-Polarimeter. We also discuss unique and efficient approaches to
the ATST instrumentation, which builds on the use of common components
such as detector systems, polarimetry packages and various
opto-mechanical components.
