Calculating with PLank's law for black body radiation was always difficult. Here is the first sliderule to calculate spectrum values in the infrared, developed in WWII (1944) by Aristo (Aristo 10048). The cursor is fixed with 4 screws and not mobile! This rule is in BOX_JL01, and given here as an example of the evolution of thermal radiation sliderules.
