A pair of high quality 445nm laser modules

[sbk]

- Dual diodes setup, 405-G-2 lenses
- around 3.5mm at aperture, around 1mrad and stay square on far field (anamorphic prism pair on each)
- Both gives >1.8W, exactly the same since the beginning, they are not overdrived so a long lifetime is ensured
- Picodrive driver RBLD 6-ch from Laserparts.ch. Needs 5V/5A, integrated TEC driver with sensor (40mm TEC is used). Can gives max 1.1A to the diode.
- Cases are from Dave's group buy, in the beginning of 2011. Rock solid, anodized, 130x80x58mm.

They performed very well but I had to exchange them for smaller modules when I upgraded my projectors to RGB last years and since they sat on a shelf.
Note : prisms are a bit cracked, probably due to over pressure from the mount, but the cracks are far away from the beam path.
Note2 : it's advised to cool the drivers with a small fan directed to the electronics side, otherwise they heat a lot and output power decrease.

Parts only cost me 665$ each, I am expecting 350€ each. A reduction can be negociated if you buy both at one Offers are welcome too.

Are these 1.8w each laser? So 3.6w combined?

[sbk]

Each module do 1.8W yes
You can combine both modules with a PBS cube and a waveplate if you want to have 3.6W.

Nobody interested? No one is building projectors anymore here?

[sbk]

Nice case! Seems like an audio amp case? Have you already a blue module inside?

Maybe somebody will be interested by only the module without the driver (like if you have already one or want to use another one)?
Or the 6 channels Picodrive drivers without the blue module (to power a 6x red diode module)?

Seb, I would have met up & bought one from you if I was in CH for a visit, looks like a very nice module!

[sbk]

Hehe, don't hesitate to tell me if you come once to visit the country, you'd be welcome home for a laser session :-)

Yes they are nice modules, it's a shame I had to remove them from my projector due to not enough room for the rgb upgrade. Now I have even less blue power.

By the way, I'm afraid price just went down to 300€, if someone is interested...

[sbk]

Up!

300€? 250€ 50€? 10€???
