Abstract
In the usual Babcock magnetograph the sun f s image is scanned by a single exploring aperture which admits light to a spectrograph for subsequent photo- electric detection and analysis. We replace this aperture by a slit, and in the focal plane of the spectrograph a fiber-optic probe dissects the spectral and spatial image, feeding light to an array of 80 photomultiplier tubes. Magnetograms taken with the instrument show a resolution comparable to that achieved by photographic methods, but with the advantage of lower noise and direct measurement of magnetic flux.
