A Fully Tunable Lyot-Ohman Filter.
Abstract
Properties of the Zeiss universal birefringent filter and its optical and electronic interface with the Sacramento Peak Observatory's vacuum telescope are described. The instrument permits observations of solar intensities, velocities and/or magnetic fields in rapid succession in any Fraunhofer line in the 410 to 700 nm wavelength region with high spectral (0.004 to 9.013 nm) and high spatial (approximately 1/3 arc second) resolution.
