It has long been observed that the efficiency behavior of concave gratings differs from that of the well-studied plane gratings. In particular, peak values are less, and anomalies are usually absent or at least greatly attenuated. A detailed study of a typical holographic grating shows how variations in behavior over its surface combine in producing these results.
