  "term": "Blaze-angle",
  "field": "Chemistry",
  "definition": "The specific angle of the grooves on a diffraction grating relative to the grating's surface, designed to concentrate the diffracted light into a particular order and wavelength range. By shaping the grooves, the grating's efficiency for a desired wavelength is maximized. A grating is specified by its blaze wavelength in a particular spectral order for a given angle of incidence.",
