Characteristics of grating spectra

WebAug 10, 2024 · A grating for the UV and visible regions of the spectrum will between 300 - 2000 grooves per mm (most commonly 1200 to 1400 grooves/mm) and be blazed at an angle where the transmittance is best for the wavelengths of interest. Gratings for the IR where the wavelengths are longer that in the UV and visible will have less grooves /mm. WebNov 1, 2012 · This section is a discussion on the effect of n_mod and n_avg dynamics on the evolution of characteristics of FBGs written by the UVG/UVT beam.
