A Model-based Technique for Ad Hoc Correction of Instrumental Polarization in Solar Spectropolarimetry
Sarah A. Jaeggli, Thomas A. Schad, Lucas A. Tarr +1
We present a new approach for correcting instrumental polarization by modeling the non-depolarizing effects of a complex series of optical elements to determine physically realizab…
Polarization Modeling and Predictions for DKIST Part 5: Impacts of enhanced mirror and dichroic coatings on system polarization calibration
David M. Harrington, Stacey R. Sueoka, Amanda J. White
The DKIST is designed to deliver accurate spectropolarimetric calibrations across a wide wavelength range and large field of view for solar observations. Instruments deliver spectr…
Polarization Modeling and Predictions for DKIST Part 4: Calibration Accuracy Over Field of View, Retardance Spatial Uniformity And Achromat Design Sensitivity
D. M. Harrington, S. R. Sueoka
Modern observatories and instruments require optics fabricated at larger sizes with more stringent performance requirements. The Daniel K. Inouye Solar Telescope will be the world'…
Polarization Modeling and Predictions for DKIST Part 3: Focal Ratio and Thermal Dependencies of Spectral Polarization Fringes and Optic Retardance
David M. Harrington, Stacey R. Sueoka
Data products from high spectral resolution astronomical polarimeters are often limited by fringes. Fringes can skew derived magnetic field properties from spectropolarimetric data…
Polarization Modeling and Predictions for DKIST Part 2: Application of the Berreman Calculus to Spectral Polarization Fringes of Beamsplitters and Crystal Retarders
David M. Harrington, Frans Snik, Christoph U. Keller +2
We outline polarization fringe predictions derived from a new application of the Berreman calculus for the Daniel K. Inouye Solar Telescope (DKIST) retarder optics. The DKIST retar…
First spectropolarimetric measurement of a brown dwarf magnetic field in molecular bands
Oleksii Kuzmychov, Svetlana V. Berdyugina, David M. Harrington
We present the first measurement of the surface magnetic field of a late-M dwarf, LSR J1835+3259, with the help of the full-Stokes spectropolarimetry in the bands of diatomic molec…
