Abstract	A new polarized neutron spectrometer REMUR has been constructed and commissioned. The spectrometer REMUR is dedicated to investigations of multilayers and surfaces by polarized neutron reflection and of the inhomogeneous state of solids by diffuse small-angle polarized neutron scattering. The spectrometer operates in the neutron wavelength interval 1\div 10 A. In the reflectometry mode it allows one to complete polarization analysis and neutron position-sensitive detection within the solid angle of scattering 2.2\cdot 10^{-4} rad. The spectrometer ensures good statistics of the reflectometric data in the scattering wave vector interval 3\cdot 10^{-3}\div 5\cdot 10^{-1} A^{-1}. In the small-angle scattering mode the spectrometer allows the investigation of neutron scattering processes without spin-flip over the detector's neutron registration solid angle interval from 4\cdot 1-^{-3} to 10^{-1} rad and the scattering wave vector interval from 0.006\div 0.15 to 0.03\div 0.7 A^{-1}, respectively.
