Those puppies are in the mid-four figures. People who do home or business
"energy audits" have access to them. Time to cultivate some friendships!
(On the other hand, the new BLUR cameras (Backwards Looking Ultra Red) are
about the same price and would allow us to look retrospectively at our previous
attempts and collect new data from old tests..!)

Sounds like you need FLIR for this project...

Hi,
I think removing the internal IR filter works with most webcams, and if you
want to make sure you ONLY see the infrared but not the visible part of the
spectrum, you can add a filter that only lets infrared light pass. A piece of
overexposed and developed color negative film (like from the beginning of a
film roll) works quite well for that purpose. It blocks nearly all visible
light and is quite transparent for IR. If you know someone who still shoots
pictures on film or someone who did so in the past and kept the negatives, they
should be able to find a suitable piece of material.
Not sure how you want to use the IR camera, but you should be aware that it
will not be a thermal imaging device. It will be sensitive only to near
infrared, and in order to emit those wavelengths a body must be quite hot
already, i.e. close to glowing.
I have a few unused webcams at home and will check if they can be converted.
Have a great day!

Hi
I am no expert but if memory serves webcams contain an IR filter. If the filter
is simply removed the webcam becomes much more sensative to the IR part of the
spectrum.

Hi,
Does anyone know and is willing to turn a webcam into a webcam with infrared
vision for the series of motors VIC and to study the ablative materials?
