Mitsubishi ML520G71...Red Holy Grail or Flashlight Fail ??

Well...interesting...and educational...to say the least !! Of course....I NEVER say the least !!
The fun of this hobby is the journey....not the arrival. At minimum...it is a new toy to tinker with...
and who knows what innovation my arise with many, many PL'ers pushing the envelope . Most of us are not traditionally trained in Optics. So What !! T.Edison said it best....invention is 99% perspiration !! THANX for all your hard work !! CDBEAM

I don't have any free 3mm mirror scanner sets at the moment.

The thorlabs lens cost me like $80 alone. Its was the only lens I could find with high enough NA to collect all the light. To make matters worse the diode has to be centered perfectly or the spot looks like crap. Not gonna get away with a aixiz holder!

This is a really cool diode for the money IMHO. However, I believe anyone trying to put these on 3mm mirrors should really just buy the opnext diode. Press it in a mount add a cheaper lens and your done. 200mw in 2mm beam .4 mRad!

I think these mitsu diodes are best served for high power beams with big mirrors. Next I'm gonna try to get 4 on 5mm mirrors with 1.6 1.8 mRad.

We are also using a lot of these devices in applications they were not designed for.

Tried the Planters concept of using two (2) A-Prisms.....each at approx 48 degree....trying to " Dodge the Bullet" of incidence reflection. See Pic. Set the mA to 500 and got 371mW with collimination lens only. A dual set of prisms cut the PO down to 301mW....or 19% optical loss !!. The mRad with dual prisms was 2.3.....with no prisms...it looked like the visor opening on Gort the Robot !!!

I tried many A-Prism angle combinations....and....as expected....the less the angle=> the less the divergence=> the lower the transmission....TWO waste beams suck....yea...whata waste !! I think the prisms are a dead end ( I know...DUH !! )....Well....might have more luck with Lava's C-Lenses....Stay tuned for more fun with this..." Red Beam Wet Dream "

Thanks for trying this Mr Beam!

There has to be a way...

Have you seen the recent remake of that movie, it's not bad.

Well, the dude's name was Klaatu so... Maybe it was "Gort, Klaatu says WASSUP!"
