Do you have an actual 3600 l/mm grating? You should try it at CaK. As you go more to the blue, the anamorphic effect diminishes, so you need a more powerful grating to get the same spectral resolution.

I'm quite sure that the grating is 3600 l/mm, not 3200. They are supplied in the following grooves per mm: 600, 1200, 1800, 2400, 3600. This has been the standard for a long time.
