What commonly available materials will allow Infrared Radiation with wavelength of $12\,\mathrm{\mu m}$ to pass through?

Commonly available is something that can be obtained easily for manufacturing.

Thanks,

Germanium, Zinc Selenide, Barium Fluoride, Sodium Chloride, and Potassium Bromide all pass 12 $\mu$m radiation, and are easily available. Whether or not they are suitable for your application is another question entirely. I think most can be machined by diamond turning, but some, the last two in particular, will become cloudy in humid conditions.

  • $\begingroup$ What do you mean by "sheet-like"? What are you trying to make? $\endgroup$ – garyp May 22 at 10:43
