Non-standard pitch GRIN lenses

I'm working on an experimental setup and this group has been very
helpful in the development - thanks everyone! I am currently trying
to find GRIN lenses for focusing 635nm light from a single mode
fiber. I would like to find a GRIN with 0.3 or 0.31 pitch, which is a
bit longer than the readily available 0.29 pitch lens. I've tried
Google, GlobalSpec and optics.org and the only company I could find is
Grintech, who said they could make the lens but in minimum quantity of
50 pieces. Can anyone suggest any alternate suppliers? Thanks for
your help!
