It all depends on what you want to achieve. Each bands have pros and cons.
For instance, a cooled LWIR surveillance system can show better atmospheric penetration upon certain atmosphere, compared to MWIR. But LWIR lenses need to be faster (smaller f#), due to the diffraction limit. This drives larger lenses, hence bigger, heavier and more expensive systems. MWIR can be a good trade off, but again, it depends on the mission to accomplish.
On measurement systems, it mostly depends upon the type of experiment and/or measurement conditions. We are here for you to help define the best suitable configuration. And if it’s a technology we don’t use, that’s also fine to let you know and give you workable answers.
