We outline polarization fringe predictions derived from an application of the Berreman calculus for the Daniel K. Inouye Solar Telescope (DKIST) retarder optics. The DKIST retarder baseline design used six crystals, single-layer antireflection …
We report on the performance of a vector apodizing phase plate coronagraph that operates over a wavelength range of 2-5 μm and is installed in MagAO/Clio2 at the 6.5 m Magellan Clay telescope at Las Campanas Observatory, Chile. The coronagraph …
Improving the polarimetric sensitivity by understanding beamshifts
This Field Guide is a concise, organized reference that explains the functions and configurations of astronomical instrumentation. It provides an overview of aspects of astronomical instrumentation from principles of general optics and optical design …
Astronomical adaptive optics technology is used to dramatically enhance the spatial resolution of in-vivo two-photon microscopy of thick optical tissues.
