Изобретение относитс к спектральному приборостроению.This invention relates to spectral instrumentation.

Известны дифракционные решетки со штрихами ступенчатого профил , у которых угол между .рабочими гран ми всех штрихов и плоскостью делени есть величина посто нна .Diffraction gratings with strokes of a stepped profile are known, in which the angle between the working faces of all the strokes and the division plane is constant.

Цель изобретени - увеличение разрешающей способности и светосилы.The purpose of the invention is to increase the resolution and luminosity.

Дл этого в предлагаемом устройстве рабочие грани всех штрихов наклонены к касательной ее образующей под одинаковыми углами .For this, in the proposed device, the working faces of all the strokes are inclined to its tangent forming at the same angles.

На чертеже изображена схема предлагаемой вогнутой дифракционной решетки.The drawing shows a diagram of the proposed concave diffraction grating.

Слой 1 металлизациии, на котором нарезаны штрихи 2 дифракционной решетки, жестко скреплен с подложкой 3.Layer 1 metallization, on which the strokes 2 of the diffraction grating are cut, is rigidly bonded to the substrate 3.

Решетка нарезаетс таким образом, что рабочие грани 4 всех штрихов наклонены к касательной 5 ее образующей под одинаковыми углами А.The grid is cut in such a way that the working faces 4 of all strokes are inclined to the tangent 5 of its generatrix at the same angles A.

Предмет изобретени Subject invention

Вогнута дифракционна решетка со ступенчатьш профилем, отличающа с тем, что, с целью увеличени разрешающей способности и светосилы, рабочие грани всех штрихов наклонены к касательной ее образующей подA concave diffraction grating with a step profile, characterized in that, in order to increase the resolution and luminosity, the working faces of all strokes are inclined to its tangent forming

одинаковыми углами.the same angles.
