Transmission curves with the combinations of (a) the mechanically ruled 800 lines mm−1 grating and M2, (b) the holographically recorded 800 lines mm−1 grating and M2, (c) the mechanically ruled 300 lines mm−1 grating and M2, and (d) the mechanically ruled 800 lines mm−1 grating and M1. All the spectra were measured by the photoemission current from a gold-coated tungsten mesh. |
