I've got an Oriel 7240 monochromator here with a 150 line/mm, 4 micron
grating in it. I'd like to find a 1200 l/mm grating, preferably blazed
for 700nm since I'm most interested in 600-900nm. Does anyone have one
for sale (or trade for my 150 l/mm grating)?

That's similar, but the 7240 uses a 30x30mm grating attached to a mount
with 3 small pins adjusted to that gratings can be swapped without
having to realign the machine. I might be able to remove the 150l/mm
grating and replace it with a 1200l/mm one, but it would have to be 30x30mm.
