ABSTRACT:
The invention constitutes a method of and apparatus for measuring the absolute wavelength of a source of unknown frequency radiation through directing radiant energy of known frequency against a diffraction grating of predetermined pattern so as to image a calibrated scale on a suitable screen or the like, and then directing the radiant energy from the unknown frequency source along the same path to the diffraction grating and onto the screen, where a visually available easy-to-read measurement of the wavelength appears.
