Welcome back! This is Part 4 of a 10 part series on the "10 Things You Need to Know About Infrared Inspection Windows." It is essential for a thermographer to know the transmittance rate of the IR window that they are about to scan, otherwise the measurements recieved from the inspection are null and void. However simply knowing the windows transmittance rate may not be enough as on crystal windows this value changes over time. Martin Robinson, CEO of IRISS explains why this occurs and how to deal with it in Part 4 of this webinar series.
To review, Part 1 gave you a detailed outline on exactly “What is an Infrared Inspection Window?” and what is the purpose of IR Inspection Windows. If you missed it, click the picture below to catch up.
Part 2 gave you an in-depth look at the material used in IR Windows. You can now answer the question, “What material is used in IR Inspection Windows?” You also learned that there are materials that are used that are not safe for certain environments.

Part 3 showed how emissivity is essential to getting true readings during IR inspections and that if a target is a poor emitter then it will actually reflect temperatures from other components close to the target object of the scan.

After watching this informative webinar, you can answer the question, "Why is knowing my windows transmittance rate important?" You will also know that the transmittance rate of crystal IR windows changes overtime as the windows degrade, which leads to corrupt readings overtime.
