Yes, but you will not get the lenses AR attributes effecting those wavelengths. It's best to get a lens designed for the wavelength you intend to use it on, or one that covers a range of wavelengths (again the ones you intend to use it on).
^ other than this, green modules (cause i suppose you are speaking about DPSS modules, for green, and not pure diodes) have lenses with focal lenghts from 6 to 15mm, depending from the expander ..... a short 2 or 3mm FL for a green module is almost unhelpful, focusing it can become a nightmare
the 405-g1 lens doesnt lose much with red at all!
the virtualvillage one is 5% better than stock aixiz, the 405-g1 is 5% better than the virtualvillage, and the red-coated meredith is only a few % better than the 405 one!
the 405-g1 is the one with the shortest focus available, so i chose it for my red built too. a few percent lost, but much higher powerdensity from the thinner beam.. worth for me, ymmw!
You're correct, though for optimal results an AR coated lens that includes the frequency being used is needed (you did mention that though). Others will work, and a few percent is probably not a big deal for the general hobyist. Just wanted to point out that there will be a difference, even if it is small.
Btw, I've looked at your projects, you do some fine work.
