Assumptions & Legal Notes
All calculators provide indicative values based on simplified models. Results depend strongly on beam quality, optics, detector characteristics, alignment, material properties and environmental conditions.
Outputs must not be used as the sole basis for safety classification, certification or compliance decisions.
