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
chad

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.:cool:

More testing to come.:beer:

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