WS-PI,
Sorry I cannot agree with you there. I am very familiar with NUC and FFC and their operation. I repair and service thermal imaging cameras for fun

The key difference is that NUC is set in correction tables at calibration and may be considered a 'course' correction for
individual pixel characteristic differences. The Microbolometer is a tricky little array that is hard to keep uniform as its temperature changes. The FFC uses a shutter that passes in front of the microbolometer and then equalises the
small differences in individual pixel outputs to produce a flat field. A sort of fine tuning of the microbolometer. It is VERY unusual to have the sort of gradient across the microbolometer that appears on the SEEK. Such a large and block type gradient would normally be cause by poor hardware design and that is not the purpose of NUC or FFC. They are there to correct the natural characteristics of the microbolometer.
If the gradient in the SEEK were a simple NUC issue, it would have been caught during calibration and corrected. Such would have been a simple fix and we would not have seen the number of SEEK cameras with a gradient issue over an extended period of production.
Please do not think that I have a grudge against the SEEK camera. I am positive on the product objective, disappointed with SEEK Thermal as a company, and technically incisive on the SEEK camera design, which is flawed. Engineers analyse designs and comment on such, that is all
