Do you mean for the mirrors on the galvos?

Hi.

No, I mean the glass protecting the Galvos output.

You can use regular glass to be honest ... you'll just lose a chunk of power 5-10% or so.

You can get AR coated glass here: Anti-Reflection (AR) Coated High Efficiency Windows

As far as I can see all of the windows on that page are broadband (425nm-700nm) AR (Anti-reflection) coated. Just need to pick a suitable size and double check the specifications to see if it meets your needs. Loss with AR coated glass is more like ~1%.

There are other sources - search around for AR coated glass. Maybe search on Photonlexicon - there have been threads about this before.
