$2300 ?????????

That's not bad at all! For 500mW of deep blue! Do you know what the emitter size is?

Dave;

Am I reading this right? $2300 each when you buy a lot of 10 of them? So $23,000 gets you ~ 5 watts worth of 445 nm blue? (Assuming you can combine the beams from all 10 diodes, which is a huge chore in itself...)

That's a pretty good deal, compared to the cost of even a 1 watt DPSS blue at 473 nm...

Hello!
First, the Emittersize of blue Diode lasers are verry small, so it is ~0,4µm....
BUT the problem is that the Emitter has 7-9°/40° , and you can only colliminate 7-9°/16-19° good. So you must use a special Aspheric lens...
But don´t think that you can use this lens also for red! The highpower red hase same emitter 7-9°/40°, but an thick Emitter withh 100/200µm.
Greetings,
Phil

WoW! I would very surprised if it had a emitter less then 50uM. There is no way it is getting 500mW out of a 4um emitter! Sorry

Figure on throwing away between 15 and 25% of the power when bundling them into a good spec beam as well.

You got it

[Lasercingi]

The beam divergence full angle : min/max 7-25°/30-50°
I don't know the size of the emitter :-(
Operating temperature: 20-30 °C

I think the stripe size on the 1/2 watts is around 8um, and the 1 watt stripe is 15um (this is off the top of my head).
