RE: [APML] O.T.: infrared

["Richard Klappal" <klappal@xnet.com>]

According to the chart at Lawrence Berkeley Labs
(http://www.lbl.gov/MicroWorlds/ALSTool/EMSpec/EMSpec2.html), that's about
right, but I don't think that "photographic" infra-red extends that far.

Kodak hi-speed infrared reaches to +/- 925nm.

I suspect CCDs range all over the place.

Hello group:

Does anyone know the range for infrared in wavelengths?  I have found
variable numbers quoted and would like to print the correct range on my
infrared photography web page.  One source said 700 nm to 2 mm, which seemed
quite large and did not match the other examples displayed graphically.
