600 mW of 650nm red from a single diode!

Hi John,

I will call Casey tomorrow, I haven't talked to him in a while and need to catch up. I can't remember if he has it or if Kyle has it. I will find out.

And it very well could be a butter dish

here u go guys a 500mw 670nm diode

Andy, we were looking for 500 mw of red at 660 nm, or better yet 635 nm. Also, we wanted the beam quality to be close to that of a 660 nm Maxyz module.

670 nm is just too far down in the band to be really useful. You'd need something like 3-4 watts to make it look as bright as 500 mw of 635 nm red.

Besides, if I'm reading the .pdf scpec sheet for that diode correctly, it's got the divergence of a floodlight! No good for our use. If you decided you were going to use 670 nm anyway, you'd be better of going with 671 nm from a DPSS solution. At least that way you could get multiple watts of power and still have great beam quality. (But you'd still have the problem with low visibility, not to mention the cost!)

I have such a diode of 500mW 671nm. I think it may be fun to add some deep red to a projector.
The divergence is very nice! Keep in your mind that the divergence in the datasheet is directly out of the diode.
Compare this to some 635 or 658nm and I think the beam after collimator will be very nice.
But indeed visability is low of 671nm!

What kind/make of diode is that?

The link is a few post above. Here is the datasheet:

Sony made these diodes.

Wow, with those rounded corners and off-white color, all you have to do is cover the rear in some bakelite and you have yourself big red from the '40s'

[chad]

Totally, Then all you would need to do is add one of these for the emission indicator

Yeah, and lots of chrome, everywhere! And maybe some big rocket fins in the rear

Hi, I had a Sony SLD1332V a few weeks ago (from BFI Optilas, ist was about € 360+tax) but it was dissappointing because of the 100µm stripe, also it can only be operated at 25°C (TEC and precooling must have).

Additional, the 671nm made the (fat) beam pretty dark.

I sold it on ebay for poor €160
