fitting beams into smaller scanner mirrors?

[planters]

Hm, how about using two pairs of cylindrical lenses to shrink the beam? One for the horizontal plane, and then another pair for the vertical? This adds losses but those lenses are easily sourceable.

These lenses are more available than PCX and PCV lenses? Well, if so, yes, this will work.

At a similar price range, and only from what I can tell. Can't find on eBay except for CO2 lasers, don't think the Surplusshed ones are coated well and the ones Edmund Optics sells are around 4x as much as buying 2 pairs of cylindricals. http://www.edmundoptics.com/optics/o...x-lenses/3212/
Not sure if I've found the right type of lenses (by material) at the Thorlabs website. If yes, the cost looks almost the same as Edmunds. https://www.thorlabs.com/newgrouppag...tgroup_id=6560
