Buy: diffraction grating

[atomd]

Hi,
I'm looking for 1200 lines/mm reflective diffraction grating. Can be really small (6x6 mm minimum). Anyone has something reasonable for sale?

I've got a sheet of 1000 lines/mm. Could send you a small piece in an envelope if you give me your address. It's not reflective though.

Nah, PET transmissive gratings I also have. For ECDL I need grating specifically in littrov configuration and somehow Chinese $25 models disappeared. The best I found is $80 at EO, I'm hoping someone here has leftover grating or small cutout from some project.
