FIELD: physics; technological processes.
SUBSTANCE: method of diffraction gratings manufacturing includes application of thin layer of magnetic liquid on substrate and influence with magnetic field on it. Thus for obtaining of hexagonal structure, thin layer of magnetic liquid on substrate is applied in the field of homogeneous constant magnetic field guided perpendicularly the plane of glass plate, forming system of identical drops. For obtaining of band structure use the nonuniform magnetic field guided under an acute angle to the glass plate plane. Magnetic liquid having highly volatile basis is used in the method.
EFFECT: reduction of material and time expenses at diffraction grating manufacturing.
