Interest gauge for 250mW

[daedal]

This is to gauge interest in the 250mW 640nm diodes from OpNext.

The datasheet can be found here:
http://www.laser-diode.co.uk/product...t/hl6388mg.pdf

The current price is around $210 in quantities of 25 to 99.
Shipping + optional insurance will be extra, and per order.
Domestic will be around $5 and international will be around $12.
All prices are in US Dollars.

If we get 25 or more interested parties, we can go ahead with the group buy.

Please post below if interested.

Thanx;
DDL

Daedal- you have a design in mind for our multiwatt red?

what could we do with 20 of these?

Ill buy 10,.......... If somebody designs a way to put them together for 2 - 2.5 watts of red

LETS SEE... 10 X 210.00 = 2100.00 $ +++ ----> ~ 2 WATTS OF 640NM
OR........... 5,600.00 $ ----> KVANT 2 WATT OF 640NM

Hehe
You have forgotten something on your calculation.
High quality Polecube, High quality mirrors, High quality waveplate (Labmbda/2 plate), good stable mirrormounts, milling part, really good lasercollimation optics, Laserholders, and still good quality drivers, Telescobe optics, and the knowledge to build a red such this with a good stability and long lifetime.

Ahyes, the 250mW Opnext, they are likely the same as the 150mW Mitsubishi 640nm ... 4*1mm beam and 2mrad or so, so not really interesting beamquality. You should better choose the 150mW types if you want to have a good beam quality.
And yes, don´t forget the losses, each build has losses.

hi Phil,
who am i kidding, this build would be above my paygrade,, i think i will let the pro's do the dirty work, and ill just pay for the completed module

I second that

Whereas this, the KVANT unit doesn't seems that expensive.

As if he knows what he is talking about...

Is "this" in there somewhere?

[Phritzler]

Hello!
No, a Smaller size, higher power (more diodes) ande more stable one.
