NIRC2-Pol: First Light of Near-Infrared Polarimetry on Keck II
Briley L. Lewis, Manxuan Zhang, Maxwell A. Millar-Blanchaer +21
NIRC2, the Near Infrared Camera 2 on the Keck II telescope, was recently upgraded with a new suite of polarimetric observing modes. The new polarimetry modes (referred to as NIRC2-…
Enabling Quantitative Polarimetry for Keck/NIRC2: Preliminary Mueller Matrix Model Calibration
Manxuan Zhang, Briley L. Lewis, Maxwell A. Millar-Blanchaer +27
The Keck/NIRC2 infrared imager was upgraded in 2025 with dual-beam polarimetric observing modes spanning approximately 1.1--4.1 microns (JHKL' bands). We present a preliminary JHK…
The Space Coronagraph Optical Bench (SCoOB): 11. Modeling and correction of chromatic aberrations
Kyle Van Gorkom, Ramya M. Anche, Saraswathi Kalyani Subramanian +12
The space coronagraph optical bench (SCoOB) is a high contrast imaging testbed designed to demonstrate starlight suppression techniques at visible wavelengths in a space-like vacuu…
The Space Coronagraph Optical Bench (SCoOB): X. Dark zone maintenance
Saraswathi Kalyani Subramanian, Kyle Van Gorkom, Ramya Anche +12
The Space Coronagraph Optical Bench (SCoOB) is a vacuum high contrast imaging testbed designed to demonstrate starlight suppression at optical wavelengths and obtain contrasts bett…
Design and modeling of an oblique incidence dichroic mirror for a high contrast imaging system
Joanna Rosenbluth, Ramya Anche, Kyle Van Gorkom +4
The proposed Habitable Worlds Observatory (HWO) aims to detect and characterize Earth-like planets around Sun-like stars from the ultraviolet to the infrared using high-contrast im…
The space coronagraph optical bench (SCoOB): 3. Mueller matrix polarimetry of a coronagraphic exit pupil
Jaren N. Ashcraft, Ewan S. Douglas, Ramya M. Anche +4
High-contrast imaging in the next decade aims to image exoplanets at smaller angular separations and deeper contrasts than ever before. A problem that has recently garnered attenti…
