With the NSO low-order adaptive optic system at the NSO Dunn Solar Telescope it is now possible to perform spectroscopic measurements at high angular resolution and high signal-to-noise level. The performance of the AO system for spectroscopic investigations will be demonstrated.
By using a dual Fabry-Perot spectrometer we obtained spectral line scans of active regions with a spatial resolution of 0.3 arcsec at 557nm. We use these data to adress questions of magnetoconvection in active regions.
