Canonically Blazed Transmission Gratings: Analysis and Modelling Results

In this paper we present a blazing scheme they may be generated on any rectangular grating and that is sufficiently general to cover all conceivable cases of linear blazing imposed on rectangular transmission gratings. Characterizing the blazed grating completly by a group of parameters, we develop the analytical formula for the intensity spetrum of a blazed grating set perpendicularly to the irradiating light in terms of these parameters. The analysis given is valid for the regions of material properties and light energies where refraction may be ignored. Practical implications of the modelled equations are discussed and are shown to have great potential in the development of new instrumentation in the soft x‐ray range.
