摘要： A plane grating, particularly for a monochronomator, is provided with varied-spaced straight and parallel grooves in a light beam path to compensate for other light affecting components, for example a spherical mirror used for collimating or focusing the light beam. The angle of incidence with respect to the light for each of the grooves may vary and the angle of diffraction with respect to the light for each groove may be required to vary with the imperfection of collimation and focusing of the beam. The grooves are varied in their spacing to compensate for the variation of both incidence and diffraction direction.

摘要： The invention relates to a monochromator which disperses the light containing many wavelengths emitted from a source of light, and which takes out a given wavelength component only. The invention realizes a monochromator which can take out the light of a single wavelength maintaining a very high wavelength purity by using a plane grating C which can be easily manufactured maintaining a high precision and by employing a very simply constructed wavelength sweeping mechanism in which the distance between the incident slit A and the diffraction grating C as well as the distance between the exit slit B and the diffraction grating C are maintained constant, instead of using a concave grating that had been indispensable in the conventional monochromator adapted to the wavelength regions of from soft X-rays to vacuum ultraviolet rays.

摘要： A tool for ruling grating grooves is reciprocated on a diffraction grating blank with the tool being restrained within a plane inclined at an arbitrary angle relative to a plane lying in contact with one point on a spherical concave of the diffraction grating blank. Translation for a variable pitch-groove spacing which changes as a function of the groove number or groove position is imparted to the diffraction grating blank in interlocking relationship with the reciprocation, thereby mechanically ruling the desired sphere of the grating blank with the grating grooves, whereby a concave diffraction grating which forms diffracted light of a specific wavelength into a completely stigmatic image at high diffraction efficiency can be manufactured.
