It's very sad that there is not a universal naming convention, but it really comes about because of the multiple fields that utilize the EO/IR spectrum. CIE recomends a FAR UV, UV-C, UV-B, UV-A, VIS, IR-A, IR-B, and IR-C; Astrophysics has Extreme UV, Lya, FarUV, MidUV, NearUV, VIS, NIR, Mid-IR and Far Infrared (FIR); Atmospheric Science has UV-C, UV-B, UV-A, VIS, NIR, IR, Thermal Infrared, and Far Infrared; Military is Vacuum UV, UV-C, UV-B, Solar Blind UV, UV-A, VIS, NIR, SWIR, MWIR, LWIR, and FIR That's just the four groups I can remember off the top of my head.

As you can imagine, almost none of them define the spectral bands the same way ... even when the name is identical.
From what I can tell, most IR camera vendors lean toward the military convention at least MW and LW.
Side note: Inframetrics did something similar to Agema. Their 760's were name SW, LW, and BB for their cameras. However the SW was nominal 3-5um, LW was nominal 8-12um, and the BB was a nominal 3-12um
