NIST PAPER - Pointer IR

For those who do not know, National Institute of Science and Technology are the folks who do the US National standards of time, frequency, mass, temperature, standard materials samples, and a whole lot of other very useful things, including research assigned to them by congress etc.

With the caveat that silicon sensors in web cams are lousy sensors for 1064 nm light, even when "modified" or designed for night use, enjoy:

The above paper was designed to be educational, not as a formal study, so they will not name the manufacturer.

Hey that's really useful to know! I think I'll setup a few of those experiments today, it will give me something to do..

Ah I see now.. they used the repair faq as a reference!

Interesting read....

I am surprised that Digital Cameras can not see 1064nm...
and that most of the IR leakage came from 1064nm and
not just 808nm...

Thanks for sharing and enlightening me...

Jerry, I just attached a silicon response curve to this post. Curve is from Edmund's website.

from my experience the attached curve is generous at 1064, most are a bit further down then that.

Thanks, i have enjoyed reading it.
