Update for 445nm Laser Diodes
I have a 445nm Laser Diode in route for Power Testing.
HeatSinking will be critical for high power levels from these 445nm diodes.
I think a High NA lens will be required for good power outputs from the 445nm diodes.
Users have reported ~ 26% increase with High Power over stock Aixiz acrylic lens assembly.
Testing will confirm these field reports.

Edison;
This 445nm diode has presented some unusual challenges in beam correction.
It has different diode projections from other laser diodes I have worked with.
I analyzed the beam from the diode focused to 10 ft. last night.
The beam started with a vertical bar pattern at a couple of inches,
changed to a round dot pattern at 1-2 feet,
and then changed to a horizontal bar at 10 feet.
You can adjust the beam pattern slightly by defocusing the beam at most distances.
A cylindrical lens is a good solution to eliminate the difference between the fast and slow axis.
I would order several FL's if you are doing scanner work.
The cylindrical you mentioned is not a coated lens, so you will lose a little power.
Otherwise, it seems likes a good test candidate.

Thanks RA_pierce
I,m still waiting on the driver for my setup to combinding red 640nm diodes.
I have a dual en quad setup ready. If those work i can give the plans for the 6 and 8 setup. I,m also busy with finding the best lenses for combinding the reds and i have a good feeling of the ones from Larry. With a single lens the losses are lower then a triple because of the 3 coatings. I,m very interested in your test of the cylindrical lenses. I think larry is also busy with taming the blue beast
