Measurement of emissivity of low-emissivity coatings using a thermographic camera

The development of low-emissivity coatings has gained prominence in recent years due to their various applications in the architectural and industrial sectors.This is due to their ability to optimize energy efficiency by reflecting infrared radiation while allowing the passage of visible light.When working with these types of coatings, it is essential to measure their emissivity.Therefore, this work presents a method to determine the emissivity of these coatings using a thermographic camera, addressing the limitations of traditional spectroscopic methods.
