(a) Dispersion efficiencies of the three gratings (1200 lines mm−1) presently used in MoLES, blazed at (i) 250, (ii) 630 and (iii) 900 nm. The gratings are commercially available from www.jyhoriba.com
. (b) Quantum efficiencies of the photomultiplier photocathodes, as used in MoLES for (i) bialkali, (ii) GaAs and (iii) GaInAs:Ce photocathodes. For full information, see www.electrontubes.com
