Infrared Magnetograph at Big Bear Solar Observatory

Abstract

With the support of DURIP funding, we have developed the hardware leading to the world's only filter-based magnetograph for the near IR. The heart of such a system includes a Fabry-Perot filter following a prefilter which is sufficiently narrow to ensure that it knocks out all the side bands of the Fabry-Perot (i.e. the filter's pass band is narrower than the free spectral range of the Fabry Perot) . The required IR Fabry-Perot system exists; we have purchased one from the Queensgate with DURIP funds. Nonetheless, there are no such magnetographs, at present, for measuring the evolution of magnetic fields in IR.
