Hes only using the lens & mount from the Plasmon. I'm hoping with either extra heatsinking or very brief shots.

Heres a few shots of the business end.
Using the stock diode mount I have to keep the duty cycle to 30-40 seconds, these things get warm quick!

But heh...its just a quicky to get it up & running before it goes into something a bit more meaty;)

I am sending one of these module/lens to Jayrob for testing so hopefully he will be able to give you the beam specs, I dont have a clue apart from it 'looking good'

More beam shots soon:yh:

Its the best you can do, if you don't have goggles. Although, everyone with one of these lasers SHOULD have goggles, but turning down the power a bit is still wise.

Going from the beam shot, the divergence doesn't seem to be nearly as bad as what we were worried about.

I've measured 1.6 mrad on the fast axis and .19 mrad on the slow axis on the 1/2W lab module I just put together. The beam is flat, but the divergence isn't bad at all IMO.. this is using a 405nm Aixiz glass lens.

Hmm I was under the impression the aixiz 405 glass fixed the beam a little better than that. Do you happen to have one of Jays, or Larrys lenses to measure the divergence?

No.. but jayrob did a side by side comparison here that shows that the Aixiz glass lens gives the cleanest beam profile. I'm more than happy with 1.6 mrad from a multimode diode.

Did you actually measured the beam diameter at aparture?

btw: really awesome beam! :beer:

Thats a great link, thanks!

This is only a rough measurement.... 2.0505220604755174 mRad

5mm @ aperture, 25mm @ 32 feet

Hi to another North Londoner ;-)

I'm confused about this though. If the LD is 405nm then how is it producing blue?!
