Lazeerer,

Can you give some near field measurements on the beam size right after the lens for both diodes?

Sure thing. When ii get back home in a couple hours i will take the measurements for you.

Any idea how many diodes are in the "pan" device?

There are 30. All the details are on the last page.

Lazeerer thanks for taking the time to test the lens I sent. Looks like they may be a winner just unfortunate they are so big. That is a very small power drop for the amount of correction over the G-2. Glad I still have about 15 of these left.

Duh, sorry.


thanks

BUMP!

Got home to late last night from work sorry about that.

I measured with the Pan Lens to be 6.4mm and the G lens to be 5.1mm... I would give a .2mm +/- Error room as its quit difficult to capture this.

For accurate divergence calculations we need both width and length of the spots.

38.69 / 28.41 mm is fast axis 5.1 / 6.3 is slow axis.

Just fired up my first PL520 and I have to say it was way brighter than I expected them to be.

More testing to come.

Thanks for the info. Really looking forward to playing with one of these.
