A free resource about Spectral Emissivity & Spectral Emittance, the important optical properties of matter used in Thermal Infrared Thermography and Thermal Radiation Thermometry.


Learn about emissivity basics & why Total Emissivity is the wrong parameter for Thermal Infrared Imaging & Thermometry on our 2003 Emissivity Trail Page.


Learn from Success. Why re-invent the wheel? IR Thermography & Thermometry have been used for many years, but poorly described. Here's a database of successes!
