BUYING: 1200lines/mm diffraction grating

[atomd]

Hi,
I'm building ECDL and looking for grating to lock the resonator. Preferably blazed around 520nm, but I'm open to any offers. The grating can be a bit denser or a bit more sparse but somewhere in 1050-1450.

Hi,

I can help, probably... I've built plenty of ECDL's and have left over gratings. I'm leaving for a trip but will return next Sunday.
Send me a message. What wavelength of ECDL are you building?
