'[EE] IR emitters'

Anyone know of sources for high power emitters in 800-900ish nM wavelength,
at reasonable prices?
I'm thinking something similar to the 1W and 3W visible leds.

       Digikey has the OP290 from Optek, 890nM, 5A @ 25uS, etc...

Works for pulsed apps, but the continuous rating is only 100ma.

I have yet to come accross any that large, people usually end up clustering them, although i dont know your project and that may be impractical. They dont appear to be easily available above the 250mA mark (pretty hefty led).

Laser diodes in that wavelength range can reach up to about 5W.
Manufacturers include Spectra Diode Labs, JDS Uniphase, Melles Griot,
etc.

You might need some optics to shape/diffuse the emitted beam, though, so
you won't burn anything by mistake :-)

True, but pricey, and as you mention, inconvenient beam shapes.

Lots of stuff, including many high power IR LEDs and lasers.
There is a pricelist linked from the main page so you can judge reasonableness..

Ah!  That's what I was looking for.

Pity about the price sheet, it's HUGE, and should have been broken up into
sections..

Thanks though, that's what I needed.
