Measurement accuracy is a perennial topic among thermographers. Many are unaware that improperly cleaning lenses can have significant impact upon the accuracy of an infrared imager.
Lenses and optics are an integral part of any infrared imaging system. Most infrared optics are coated with special anti-reflective coatings to maximize the transmission of infrared energy to the system’s infrared detector. For imaging radiometers, each lens is individually calibrated to the imager.
Traditionally, two different non-destructive technologies have been employed to test steam systems – contact ultrasonics and temperature measurement. Used individually, each of these techniques has limitations that can lead to false positive and/or false negative results. Combining temperature measurement with ultrasound can result in a highly accurate test method by following a few simple steps:
Always be sure to follow appropriate safety precautions especially when working with high-pressure steam or when using ladders or lift equipment.
Now in its 31st year, IR/INFO is the original Advanced Infrared Training Conference, Technical Symposium, and Technology Expo. IR/INFO features four days of networking, learning, and fun in a professional, yet relaxed, family atmosphere. IR/INFO is scheduled for January 19 – 22, 2020, in San Antonio, TX.
IR/INFO is a must-attend event for all manufacturers and distributors of infrared equipment, condition based monitoring tools and services, reporting software, and those who provide products or services of interest to thermographers.
