This site is for those who want or need to know more about spectral emissivity, what it is, how it is measured, reported and applies, or is applied to, Radiation Thermometry, including the two dimensional variation known popularly as Quantitative Thermal Imaging, and Spectral Radiometry.

The concept of this site is two-fold.

First, the staff at, the originators of the site, are organizing it and adding as much information as we can reasonably find.

Second, this is a community website. User inputs are encouraged and everything that goes on here is available to the public at large on the Web free of charge.

If you have or find an interesting resource that is not already here; share it in turn!

You can add a comment below any detail page, see the “Article Categories” list in the sidebar, at any time, or on our special comment form page by Clicking on the word “Suggest” at the top of the page or here.

We can use all the help we can get and you will get credit for everything you do, that’s the main reason we ask your name and email address.

We reject spam inputs the best we can, too, that’s a second reason we request your name and email address when you suggest something. If you are a spammer, you will be banned from the site after one submission.

By the way, the Categories list show how many articles are listed in each category, so the places we could use additional inputs are obvious, we think.

If you want to be involved, contact our leader at: grp at MrPyro dot com, or visit our other websites at IRWeb.INFO, About Temperature Sensors, and TempSensor Directories.

One thing to note, the only advertising on this site will be text-only, if we add any, to help defray, Inc.’s cost of operating it. I expect it to be minimal since our costs are actually quite low.

Thanks for visiting and do come back!
