The test units from the final manufacturer have arrived and check out good. They are broadband coated < 0.5% reflectivity. The final total losses including bk7 glass are 3%, vs an estimated 10% for prisms. <0.9 mrad emission is achievable with these (after an ashperic collimator) used to expand the slow axis of 445nm diodes and other multimode diodes with similar emitters, incl. the 500mW reds.

Beam at 56 feet (17 meters)
dimensions: 12hx9wx3t, 8hx3wx2.5t (mm)
Material: BK7
AR Coating Range: 350-700nm
Surface Quality: 60-40 Scratch/Dig
Surface accuracy: λ/2 curved, λ/4 flat
Set-up distance between lenses: 20mm
To take a note from p1t8ull,
Features compared to anamorphic prisms:
Fixed magnification setup
Less Power loss compared with prisms
Same space taken up as prisms
Beam(s) stay centered after correction optics, offset for prisms
"I can confirm that both beam correcting methods are a bit fiddly to set up, but neither should be beyond the capability for most people here if the basics are correct and time and care is taken."
These are the lenses that will be used in the Blue Lava II kit, please only order from here if you are not getting the kit, or want additional lenses. These will be ordered along with the kit lenses.
