Grating Efficiency

Spectrum Scientific has worked hard to optimize the efficiency of each of our gratings. The efficiency of any grating is dependent upon 4 conditions: wavelength, polarization, incident angle and diffraction order. Our efficiency curves are measured based on predetermined definitions of these 4 conditions. Any variation on these conditions may results in a decreased performance of the grating.
