Hi Kenn,

I finally got around to ordering some IR transmitting plastic to put in
some goggles I also ordered. I finished cutting it and went outside
just to be disappointed. All I can see is the sun. It does not look
like the goggles you guys had at the workshop. I ordered what you
listed below. My first thought was that maybe you used something less
thick, but I see that the company does not sell it thinner. I can see
really bright lightbulbs and it will transmit IR remote controls so I
figure I got sent the right stuff. I am confused. Do you have any
ideas or suggestions?

Also, did Brian ever post something online, in the way of additional
resources from the workshop? He wrote on the board that he was going to
post additional information at:
http://littleshop.physics.colostate.edu/climate.html
I still get that nothing is posted there. Do you know if he did? Or
maybe it is posted elsewhere.

Thanks!

For thermal IR, we've been using the FLIR i7 in our labs, and it
works great. No video output, but it is very easy to use, and has
stood up to student use quite nicely over the last year. For
video output (for use in lecture or such) we have a RazIR SX which
does have video output, and is quite easy to use. I have found
these both to be excellent cameras, both in lab and in class.

For near IR, you could use a sheet of IR filter over a standard
digital camera? We've ordered this (http://www.eplastics.com/Plastic/Plexiglass_Acrylic_Sheet_Infrared_Transmitting)
through a local plastic shop for use in our labs. Just cut a
small piece that attaches over the lens, illuminate your area with
an incandescent bulb (sunlight is far better), and you are good to
go. The material also works well in a pair of goggles; our eyes
are just barely sensitive enough to register the near IR. We have
our students in lab look through this plastic and see the world in
near IR for themselves.
ThinkGeek does have this (http://www.thinkgeek.com/electronics/cameras-photography/e5b5/)
camera which I have been eying for a while now. it looks great,
but I have not been able to justify the purchase to myself yet.
