~5mm beam diameter and <5mrad divergence!!?
How do you make them so bad? My Aixiz barrel and o-like lenses are better than that.

Kvant-alike too.

Shame as I might've been interested

i second that!
are you sure divergence is 5 and not .5 ?

correction optics? cooling?

**kiyoukan** · 03-17-2012, 10:02

i think they fixed it
Beam divergence, full angle(mrad): <1.5
Beam diameter at the aperture(mm): appr. 3x3.5
better a bit would be interested in how they still have specs like that when the correction is so simple.

To be honest, thats just about right to match most of my other modules. I appreciate a tighter, less diverging beam is nicer, but all things being equal, when your green is always going to be typically ~1.25-1.5mrad, what is the point of having a blue or red that is less than 1mrad

1W and a class 3B sticker?

Everything in China is 3b

They've been reading Shakespeare, 3b or not 3b...

I dont see a "beam height from baseplate" number in the specs. Since this is not standardised, it would be a handy bit of information to know.
