The linearly polarized solar limb spectrum caused by the absorption and scattering of anisotropic radiation has a very rich diagnostic potential, given its sensitivity to the thermal, dynamic and magnetic structure of the solar atmosphere.
The Interface Region Imaging Spectrograph (IRIS) provides an unparalleled opportunity to explore the (thermal) interface between the chromosphere, transition region, and the coronal plasma observed by the Atmospheric Imaging Assembly (AIA) of the Solar Dynamics Observatory (SDO).

The Chromospheric and Prominence Magnetometer (ChroMag) prototype optics under test on a lab bench at HAO. Monochromatic green light is being passed through 88mm of calcite. This is the thickest stage in ChroMag. The fringes are used to test the alignment of the optical elements and the crystal axes. ChroMag is one of the planned suite of three instruments of HAO’s Coronal Magnetism Solar Observatory (COSMO), and will be used for solar physics research and space weather applications.
