Schwelle(A limit against which other values can be compared. When a value crosses this limit, it can trigger an alert or other action); Schwellenwert(A limit against which other values can be compared. When a value crosses this limit, it can trigger an alert or other action)
Schwelle(point on the characteristic curve corresponding to the first perceptible density above fog); Schwellenenergie(energy; the minimum input energy needed to cause laser action)
