Abstract:
The performance of a grating that is elastically deformed from a sphere into a toroid is that expected from ray traces assuming an ideal toroidal surface. Thus, it has become possible to select the wavelength range, in which a toroidal grating spectrograph is near stigmatic, by adjusting the forces acting on the elastic grating substrate. The possibility of producing toroidal gratings by replication of an elastically deformed blank is pointed out.
