The Coffee Cup Test

Posted by Martin Robinson on 9/24/15 10:30 AM

A simple way to check the transmission rate of any infrared window is the “coffee cup test.” Use this test before your initial installation and during regular IR window maintenance for windows with materials that are known to degrade over time.

How Infrared Detector Response Can Wreak Havoc on Emissivity / Reflectivity / Transmissivity

Posted by Martin Robinson on 9/1/15 11:07 AM

As thermographers, we have always strived to produce the most accurate results using our thermal imagers and our spot radiometers.   Those of us that have had formal training consider many different issues when performing qualitative (temperature measurement) or quantitative (thermal patterns) inspections:

Know Your Emissivity

Posted by Martin Robinson on 4/15/15 11:28 AM

What is Emissivity?
The material emissivity (written as “?” or “e”) is the relative power of its surface to emit heat by radiation. Materials are assigned an emissivity value between 0 and 1.0. Emissivity is a measure of a material’s ability to emit infrared energy. The emissivity of a surface is the ratio of the energy radiated from it to that from a blackbody at the same temperature, the same wavelength and under the same viewing conditions.

Infrared Windows and Arc Ratings: Dispelling the Myth of “Arc-Resistant IR Windows”

Posted by Martin Robinson on 4/7/15 10:00 AM

There exists a dangerous misconception regarding the “Arc Rating” of infrared (IR) windows or viewing panes. Many reliability and maintenance professionals are under the impression that an IR window will protect them in the event of an arc blast; still others are under the impression that installing IR windows will turn non-arc-rated switchgear or electrical equipment into “arc-rated” cabinets. Neither is the case, and both misconceptions need to be corrected because they present very real safety concerns.
