ROSA (ARC, Queen's University Belfast)

The Rapid Oscillations in the Solar Atmosphere instrument is a high-cadence, high-efficiency solar imaging instrument. Designed by the Astrophysics Research Center at Queen's University Belfast in Northern Ireland, ROSA consists of six cameras, each sensitive to a different wavelength band. ROSA is capable of a cadence greater than 30 fps, and is capable of extremely high resolution, corresponding to a spatial scale ranging from 84-158 km in the solar atmosphere.

FIRS (IfA, University of Hawai'i)

The Facility InfraRed Spectropolarimeter is an advanced slit-based spectropolarimeter designed to provide simultaneous coverage of visible and infrared wavelengths. It was designed by the Institute for Astronomy at the University of Hawai'i, with support from the National Solar Observatory (NSO).  It is designed to maximize efficiency when observing the spectral lines of Helium and Iron. By positioning the spectrograph slit in multiple locations along a region of interest, FIRS can be used to build a map of the region at a high spatial and spectral resolution.

SPINOR (HAO & NSO)

The Spectrro-POlarimeter for INfrared and Optical Regions is a slit-based spectropolarimeter built by the High Altitude Observatory (HAO) in Boulder, CO, and the NSO. Up to four synchronized cameras sample different spectral lines, with up to two infrared channels, providing spectropolarimetry for much of the visible and near-infrared regime.
