Green AR coated optics at non-lab prices

[MichaelH]

Do any of you have sources for quality AR coated optics for 532nm that aren't priced for purchase by government funded labs?

I'm looking to make a collimator for my Coherent 315M and would like to minimize both backscatter and light loss through the 2-3 lenses I'll need to re-collimate (the divergence on this laser is large) the beam.

If you're doing something "custom" where a standard laser collimator won't do, then Edmund Sci's surplus division Anchor Optics has some nice coated lenses. (http://www.anchoroptics.com/catalog/product.cfm?id=368)

Otherwise a preassembled module from meredith instruments or midwest laser is a good deal.

If the prices they list is too high, I also know of some *real* fly-by-night places but your quality isn't assured.
