I bought mine over two weeks ago and its not shipped yet.
Did you buy from that seller?
Yes same seller. He replied and said they needed more time to remove the diode from the block. "might ship Monday".

Any idea how soon My ebay seller is dragging his feet:yabbmad:
I wonder if they are all waiting on the same suppliers?
Right now DTR has the M-462 that hits about 464nm on sale for 65 bucks, I know my NUBM44 is 452nm @ 5.0A and just that 7nm bump past 445nm looks great.
I imagine that 445 vs 464 would probably look a lot better in person than in pics.
Do you own any of the 462nm diodes?
I'm tempted to cube a pair just to hold me over until these are available.

I really want to see if its feasible to correct the beam after the "ball lens"
Its not a Ball lens. Its just the way the chinglish translates. Its an Aspheric
I got some good news for you that i dint pay attention at first.
I did a Test today with some more diodes with the stock lens left on it and found something interesting out.
The Lens is actually much near focus then i original thought.
The NUBM41 diode at 20 feet the dot was nearly 3 feet i was told. (This is a 450nmish diode)
I assumed that all these style diodes with the long lens can will be the same.
However the NUBM07E the dot is nearly focused. Its a hair off past columniation.
The Reason.?
Well They are using the same lens cap assemble with the same fixed lens position.
So that means because the diodes have different WL from one another and both use the same fixed lens position the focus of the lens is at a slightly different distance. So this is why you get a huge beam with the 41 diodes and a tighter focus with the 07E.
I dint catch this at first because i dint do a long distance beam shot with the stock lens. But now that i got some in to test i noticed it today.
Think of this how Thorlabs sells the same Fixed Lens here but all they do is move the fiber FC connector closer or further away from the lenses to get focus. (I have these lenses here for 660nm and 635nm) You can see each WL has a slightly Longer/shorter FL distance the fiber is away from the lens. Thats do to the different WL.

They are all the same lens.
The new G Green diode is also like this too. Much tighter focus and pretty much the same as the 07E. (Ill be posting this thread tomorrow)
Regardless though i dont like how the stock lens looks. Too much splash with it.
I catt take picture till tomorrow night but picture you have a G lens at "Infinity Focus". Give the Lens a 1/4 turn past focus and thats how out of focus it is. (Just an Example not actually same beam size)
