	We have measured the ac\&nbsp;Josephson effect\&nbsp;in\&nbsp;Nb\&nbsp;point contactsat 604 GHz (496 μm). We find the coupling of the far-infrared radiation to the\&nbsp;point contact\&nbsp;to depend in a simple manner on the\&nbsp;resistance\&nbsp;of the contact. The behavior of the high-resistance\&nbsp;point contacts\&nbsp;(50⩽R⩽200 Ω) is very reproducible, allowing a quantitative comparison of the data to the frequency-dependent Werthamer theory. We also account for the effects of noise and heating and compare these to Tinkham{\textquoteright}s heating theory.
