The performance of astronomical ultraviolet gratings is optimised in groove parameters to achieve the best average efficiency under a variable incident angle and controlled polarisation sensitivity operating conditions. After a few turns of fabrication and evaluation, good grating performance is achieved. This will be a contribution to the application of sky spectrum surveys.
