I have to say that for the past couple of hours i have been hooked by the impressive posts on this blog. Keep up the good work.

John, excellent article. It is the same principle in photography. I am glad at present, there is no zoom lens for infrared cameras.

Fixed lens allow the thermographer to frame the subject and decide where to stand to capture the image that gives you the best result.

Comment on Adjusting Level & Span Manually by John Snell

Please note in each of the 3 images of single cups, I could have narrowed the SPAN setting even more and let the table become saturated. This would have given even more thermal detail in the liquid and the cup itself.

It has always been my belief that good writing like this takes research and talent. It’s very apparent you have done your homework. Great job!

Comment on What Palette to Use? by John Snell

Thanks, Ben. One of the reasons I do not use high-contrast in the field is that it makes my brain work too hard! You might not imagine it, but processing the extra—and non-intuitive—colors is actually extra work. I find the simplicity and intuitiveness of the AMBER in particular to be much, much easier and more effective. I’ll be interested to hear what you find works best for you!

John, thanks for your tips, they are very usefull and I learn a lot by reading them.
Most of the time I use the high contrast palette and never thought about using any other in the field. I have used other palettes in reports when high contrast becomes confusing especially when the span is very small. I will definitely try the monochromatic palettes.

Comment on Correcting Measurements Through Infrared Windows by Fluke Thermography

Fluke Thermography — Tue, 13 Mar 2012 18:08:35 +0000

While degradation and moisture absorption have been historic issues with crystal IR Windows, with the Fluke exclusive ClirVu® coating, this is no longer a concern. To date, Fluke has never had an IR Window returned for this reason. ClirVu® completely coats the optic – making it impervious to moisture. Cyclic humidity testing has been performed per International Electric Code (IEC) Standard 60068-2-3, a generally accepted industry standard testing for environmental withstand capability. Fluke IR Windows have been installed in some of the harshest environments for over 10 years without incidence. These include the hot and humid Gulf of Mexico (not to mention salt water) and the brutally cold Canadian tundra. The Fluke IR Windows are also covered by a lifetime warranty.

The ClirVu® coating has a minute impact on transmission rate. It’s important to note that accounting for transmission rate consistently is more important than the transmission rate itself. The key with all infrared scans, especially those using IR Windows, is consistency. Use the same thermal imager, at the same settings, looking at the same inspection points and you will be able to compare results over time to effectively monitor equipment health.

Comment on Image Fusion by John Snell

Right on! The blended is particularly useful as you are employing it. Congrats! Glad to hear it is working well for you. Any issues I can help you with?

I am using the picture in picture and blended setting when sorting the images for reporting usually on insulation problems such as in boilers or heaters in chemical environments. Using picture in picture and blended settings when taking the images I find a bit difficult and as you say, I also want every bit of the screen to see the thermal image. I find using the blended setting very important for showing the areas of interest when looking for temperatures above a specified temperature. When we bought our imager this features was the deciding factor.
