Abstract

The Simplest Magnetograph is a novel alternative to the standard filter-based magnetograph for solar observations. The instrument exploits an asymmetry in Stokes profiles, which results in a broadband net polarization. The latter enables measurements of magnetic fields without resolving individual spectral lines. The instrument is designed to take broadband measurements of solar polarization. The chosen spectral band covers several photospheric lines with significant Land´e g-factors. While the method can be used to measure a full vector magnetic field, in our initial application we concentrated on measurements of the longitudinal magnetic field. We discuss the feasibility, design, lab testing and validation, and solar observation measurements.
