Re: infrared images



There was infrared film, might still be, but it worked in the near
infrared, not the region of the spectrum you would be interested in for
thermal scanning. Lens had may still have special markings on them
since the focal length in the infrared is not that same as the focal
length in the visible. Film would not work well in the far infrared
since you would have to keep it cold to avoid thermal noise, and of
course keeping it cold would not let the chemistry work very well, so
the available units use solid-state detectors.
Besides the power company, you might be check with larger companies that
sell windows and insulation for private homes, people who do energy
inspections, the city government, and engineering research labs.

What does is t take to take heat images of a house for example to show
heat leaks? Is there an infrared sensitv ive film that can be loaded
into a regular 35 mm camera? Does it take a special camera?
Is ther a re a print reference to doing this sort of experiment?
I know that all sorts of pictures show up in print, etc. but have not
figutr red out how to do it myself or have students do it.
Asking at usual film suppliers produced no concrete answers.
