Polarizing neutron monochromators were prepared by sputtering thin‐film multilayers with d‐spacings from 40 to 85 Å on large floatglass substrates. Peak reflectivities as great as 90% and polarizing efficiencies of 98% were measured. Increased angular acceptances were obtained by fabricating multilayers with multiple d‐spacings. A planned polarized beam spectrometer which incorporates the multilayers and which has a variable energy resolution independent of angular beam divergence is described.
