Almost, we are searching for a lens. your beam has a huge divergence, we have like 30% size of it but working to have it better with a second optic.

Also you have a hell of a lot of scatter at the diode, this looks like your primary lens is something like a LOC collimation lens and these are not good for this. We use a different one but still as cheap and it has no local scattering.

Our target is 3x3mm with < 1mrad and getting very close.

Don't want to post anything until we have the right optics selection so as not to waste anyone's time.

Nice garden.

Hello andy

i'm not very present on this forum but more on laserfreak...
your post is very interesting...
I can communicate this adress:http://www.ingeneric.com
with cylindrical lens pair - E2C module :http://www.ingeneric.com/pdf/E2X_INGENERIC.pdf
for example, i think it's possible to have a 3*3mm beam with 1mrad only 2 axis together.
on the other hand, i don't know price....
good luck...

Ex: blue 445nm nichia diode 3*3mm 1mrad housing picture

Jesus Doc, you did not look very far, I posted it there about a week ago,. SHould have just asked.

I have a second data sheet coming from the manifacturer with more specific data.

The only sheet I had seen links to was more of a brochure without the temp to wavelength graphs.
