Does anyone know of an NIR LED brighter than the SFH 4450 (in terms of mW/str)?
I'm would like to generate as bright and as small a spot as possible with an NIR (~850nm) LED. As far as I can tell, the SFH 4450 seems to be the best choice, but it is unfortunately still a little too dim for my application.
It would be great if any of you LED gurus could point me to a superior choice. Thanks!

Thanks for the suggestion but an IR laser diode is not going to work for me. First, I really need an LED since my application is sensitive to coherent noise (i.e. speckle) from lasers. Second, I need something in the NIR range (somewhere around 800-900 nm). Sorry, I should have been more specific.
