2 years ago i've bought a PD3000-rgb. Everything's fine until i opened it and see that's the bad module inside. Buying PD3000-rgb low divergence and they send me the PD3000A-rgb.
They send me the wrong item and today i contacted them for a answer.

But how to tell the difference between 1mrad and 1.3mrad if you don't realy need it.

That RGB module is sold by the same company I bought a new 5 watt version from off of ebay cheap, the seller is techhood. Mine looks almost identical inside except mine has more beam expander and collimation cylinder pairs inside in front of the diodes, you only have one.
See https://youtu.be/Soj4YXzyreU
Aaah it was you who made this video! yes I saw it and took it as an example to better understand my divergence. Thank you;)Quote:

10 watt version. Re: First photo. All of the three diodes in the upper left side are green, they have brass showing. There is a single blue diode to the right of them and on the very right most side are four red 638 nm diodes.
Thought I'd better add this photo to allow understanding the beam path better, seeing where the beam exit is.

Thanks so much for posting the 10 watt.
I came across your video a while back on the 5 watt. They had a 6 watt I purchased earlier this year that has been great. I think I purchased it for $390. Same seller as you.
I was really curious about the 10w.
I'm even more curious about the 30w.
Price per watt it's not all that bad of a deal.
