Any material transparent in 2-14 micron

At https://www.spectral-systems.com/technical-data-sheet/zns-zinc-sulfide/ the image for IR spectrum at https://www.spectral-systems.com/wp-content/uploads/2016/07/2-mm-ZnS-IR-Spectrum.jpg is missing. I am trying to find ZnS or ZnSe lenses to test an idea. But since it does not have to be durable, any solid low cost material transparent from 2-18 micron would do.

Climate Models Survey answers

I was simply checking to see how accessible and clear the data and methods, the sources and provenance of the information. If things are broken, or if they are difficult, to impossible, to access. I was checking to see if the pages were accessible to 350 Million blind or restricted vision, 450 Million deaf, millions

Akira Kokado: Gravity in a warped 6D world with an extra 2D sphere – gravitational potential models

Akira Kokado, You came up with an expression for the gravitational potential.  Did you ever convert the earth’s geopotential into your form? [ My son and his small family live in Japan.  He decided to go to college there and never came back to the USA. ] I worked with Steve Klosko on the early NASA
